Question:
If 15% of a number is 45, what is 30% of that number?

Solution:

1. Find the number:
If 15% of a number is 45, then



\text{Number} = \frac{45}{0.15} = 300.

2. Calculate 30% of the number:
Now, 30% of 300 is



0.30 \times 300 = 90.

Additional Example (Simple Interest):

Question:
A bank offers a simple interest rate of 5% per annum on a deposit of Rs.20,000. What will be the interest earned in 3 years?

Solution:

1. Use the simple interest formula:



\text{Simple Interest} = \frac{P \times R \times T}{100}

= Principal amount = Rs.20,000

= Rate of interest = 5%

= Time = 3 years


2. Calculate the interest:



\text{Interest} = \frac{20000 \times 5 \times 3}{100} = 3000.

Answer:
The interest earned in 3 years is Rs. 3000.

1. Quantitative Aptitude

Q: A sum of ₹10,000 is invested at 10% per annum simple interest. What is the interest after 3 years?
A: Interest = (P × R × T) / 100 = (10,000 × 10 × 3) / 100 = ₹3,000

2. Reasoning Ability

Example Question (Numerical Ability):

Question:
A bank offers a simple interest rate of 6% per annum. If a customer deposits Rs. 25,000 for 4 years, what is the total simple interest earned over that period?

Solution:

1. Identify the formula for Simple Interest (SI):



\text{SI} = \frac{P \times R \times T}{100}

is the principal (Rs. 25,000)

is the rate of interest (6%)

is the time period (4 years)


2. Substitute the values into the formula:



\text{SI} = \frac{25000 \times 6 \times 4}{100}

3. Calculate the interest:



\text{SI} = \frac{25000 \times 24}{100} = \frac{600000}{100} = 6000.

Answer:
The total simple interest earned over 4 years is Rs. 6,000.

Additional Example (Logical Reasoning):

Question:
In a sequence of numbers representing daily bank transactions, the amounts follow an arithmetic progression: 105, 115, 125, ... What will be the 8th transaction amount?

Solution:

1. Identify the first term and common difference:

First term,

Common difference,



2. Use the formula for the nth term of an arithmetic progression:



a_n = a_1 + (n - 1)d

3. Substitute :



a_8 = 105 + (8 - 1) \times 10 = 105 + 70 = 175.

Answer:
The 8th transaction amount is 175.
