Amortization and Negative Amortization

Question 19: Amortization and Negative Amortization

Amortization is the repayment of a loan in installments. Negative amortization occurs when the payment is less than the interest due, causing the principal balance to increase.

Debt-to-Income Ratio

Simple Math Problems

Question 15: Work Problem

A fast typist completes a task in 2 hours; a slower typist takes 3 hours. Working together, how long will it take them?

Fast typist's rate: 1/2 task per hour
Slow typist's rate: 1/3 task per hour
Combined rate: 1/2 + 1/3 = 5/6 task per hour
Time to complete: 1 / (5/6) = 6/5 hours = 1 hour 12 minutes

1 hour 12 minutes

Question 16: Train Problem

Two trains moving in opposite directions pass a stationary man in 27 and 17 seconds respectively. They cross each other in 23 seconds. Find the ratio of their speeds.

Let the speeds of the trains be v1 and v2.
Train 1 passes the man in 27s, so v1 = L/27 (L is the length of train 1)
Train 2 passes the man in 17s, so v2 = L/17
They cross each other in 23s, so (v1 + v2) = 2L/23
Solving these equations (assuming equal length trains): v1/v2 = 17/27
Therefore the ratio of their speed is approximately 0.63:1 or 17:27

17:27

Question 17: Sum of Numbers

Find the sum of all numbers between 100 and 1000 that are divisible by 14.

First number divisible by 14 greater than 100: 112
Last number divisible by 14 less than 1000: 994
Number of terms: (994 - 112) / 14 + 1 = 64
Sum of an arithmetic series: (n/2) * (first term + last term)
Sum = (64/2) * (112 + 994) = 32 * 1106 = 35392

35392

Question 18: Runs in Cricket

Gavaskar's average in his first 50 innings was 50. After the 51st innings, his average was 51. How many runs did he score in his 51st innings?

Total runs in first 50 innings: 50 * 50 = 2500
Total runs after 51 innings: 51 * 51 = 2601
Runs scored in 51st innings: 2601 - 2500 = 101

101

Question 19: Average Speed

A person drove 60 km at 30 kmph and then another 60 km at 50 kmph. What was their average speed?

Time for first 60 km: 60 km / 30 kmph = 2 hours
Time for second 60 km: 60 km / 50 kmph = 1.2 hours
Total time: 2 + 1.2 = 3.2 hours
Total distance: 120 km
Average speed: 120 km / 3.2 hours = 37.5 kmph

37.5 kmph

Question 20: Work Problem

A can complete a task in the same time as B and C together. A and B together take 10 days, and C takes 50 days alone. How long would B take alone?

Let A's rate be A, B's rate be B, C's rate be C.
A = B + C  (Given)
A + B = 1/10  (work per day)
C = 1/50 (work per day)
Substituting: B + 1/50 = 1/10
B = 1/10 - 1/50 = 2/25
B takes 25/2 days = 25 days/2 = 12.5 days, approximately 12.5 days

Approximately 12.5 days

Question 21: Boat Problem

A boat travels at 13 km/hr in still water. If the stream's speed is 4 km/hr, what time is needed to travel 68 km downstream?

Speed downstream = boat speed + stream speed = 13 + 4 = 17 km/hr
Time = distance / speed = 68 km / 17 km/hr = 4 hours

4 hours

Question 22: Profit Sharing

A, B, and C are partners. A gets 33%, B gets 1/4, and C gets the remaining Rs. 5000. How much did A receive?

Let the total profit be x.
A's share: 0.33x
B's share: x/4
C's share: x - 0.33x - x/4 = 5000
Solving for x: x(1 - 0.33 - 0.25) = 5000  =>  0.42x = 5000  =>  x = 11904.76
A's share: 0.33 * 11904.76 = 3930
approximately Rs. 3930

Approximately Rs. 3930

Question 23: Business Valuation

A person owns 2/3 of a business and sells 3/4 of their shares for Rs. 75000. What's the total business value?

(3/4) * (2/3) * Total Value = 75000
(1/2) * Total Value = 75000
Total Value = 150000

Rs. 150000

Question 24: Income Calculation

A company spent Rs. 20000 on advertising, half the rest on commissions, and had Rs. 6000 left. What was the total income?

Let total income be x.
x - 20000 - (x - 20000)/2 - 6000 = 0
x - 20000 - x/2 + 10000 - 6000 = 0
x/2 = 16000
x = 32000

Rs. 32000

Question 25: Profit Sharing

Nirmal and Kapil invested Rs. 9000 and Rs. 12000 respectively. After 6 months, Kapil withdrew half his investment. After 1 year, the profit was Rs. 4600. What was Kapil's initial share?

Nirmal's investment: 9000 * 12 = 108000
Kapil's investment: (12000 * 6) + (6000 * 6) = 108000
Profit ratio: 1:1
Kapil's share: 4600 / 2 = 2300

Rs. 2300

Question 26: Profit Sharing

Anirudh, Harish, and Sahil invested Rs. 135000 in the ratio 5:6:4 for 8, 6, and 4 months respectively. The profit was Rs. 75900. What's Sahil's share?

Investment ratio: 5:6:4
Time ratio: 8:6:4
Effective investment ratio: 40:36:16 = 10:9:4
Sahil's share: (4 / (10 + 9 + 4)) * 75900 = 13200

Rs. 13200

Question 27: Distance Problem

A travels south at 20 kmph, B travels north at 40 kmph. A turns south at 12 pm, B turns north at 11 am. Find distance between them at 2 pm.

A's distance until 12 pm: 20 kmph * 2 hours = 40 km
B's distance until 11 am: 40 kmph * 1 hour = 40 km
A's distance from 12 pm to 2 pm: 20 kmph * 2 hours = 40 km
B's distance from 11 am to 2 pm: 40 kmph * 3 hours = 120 km
Total distance apart: 40 + 40 + 40 + 120 = 240 km

240 km

Question 28: Diesel Consumption

60 liters of diesel are needed for 600 km with an 800cc engine. How much diesel is needed for 800 km with a 1200cc engine?

Diesel per km (800cc): 60 liters / 600 km = 0.1 liters/km
Diesel for 800 km (800cc): 0.1 liters/km * 800 km = 80 liters
Diesel for 800 km (1200cc): 80 liters * (1200cc / 800cc) = 120 liters

120 liters

Question 29: Distance Problem

Walking at 14 km/hr instead of 10 km/hr would cover 20 km more. What's the actual distance?

Let x be the actual distance.
Time at 10 km/hr: x/10
Time at 14 km/hr: (x + 20)/14
x/10 = (x + 20)/14
14x = 10x + 200
4x = 200
x = 50 km

50 km

Inheritance in OOP

Question 9: Advantages of Inheritance

Inheritance in object-oriented programming promotes code reusability by allowing new classes (derived classes) to inherit properties and methods from existing classes (base classes). This reduces redundancy and simplifies development.

Procedural Programming

Question 10: Procedural Programming

Procedural programming is a programming paradigm where program logic is expressed as a sequence of procedures or functions. It's a linear, step-by-step approach to programming.

Entry-Controlled Loops

Question 11: Entry-Controlled Loops

In an entry-controlled loop, the loop condition is checked before the loop body is executed. If the condition is false, the loop body is skipped entirely.

Variable Scope

Question 12: Variable Scope

Variable scope determines where a variable is accessible in a program. Variables can be:

• Local: Declared within a function or block.
• Formal Parameters: Variables declared in a function's parameter list.
• Global: Declared outside of any function.

Dangling Else Problem

Question 13: Dangling Else Problem

The dangling else problem arises in nested `if` statements where it's unclear which `if` statement an `else` clause belongs to. Proper indentation and clear structure prevent this ambiguity.

Deadlock Conditions

Question 14: Deadlock Conditions

Four conditions are necessary for a deadlock:

1. Mutual Exclusion: A resource can only be used by one process at a time.
2. Hold and Wait: A process holds a resource and waits for another.
3. No Preemption: Resources cannot be forcibly taken away from a process.
4. Circular Wait: A circular dependency exists between waiting processes.

Key differences:

`sudo` Command

Question 17: `sudo` Command

The sudo command (superuser do) executes a command with elevated privileges (typically as the root user).

Strings

Question 18: What is a String?

A string is a sequence of characters. In programming, strings are often represented as arrays of characters.

Arrays

Question 19: What is an Array?

An array is a data structure that stores a collection of elements of the same data type in contiguous memory locations. It provides efficient access to elements using their index.

Stored Procedures: Advantages and Disadvantages

Question 20: Stored Procedures

Stored procedures are pre-compiled SQL code stored in a database. Advantages include improved performance, security, and maintainability. Disadvantages include potential limitations in coding flexibility and the need for careful testing.
