Question 1

Rajesh invested ₹5,000 at a simple interest rate of 8% per annum for 3 years. How much total amount will he receive after 3 years?

Accepted Answer

Correct answer: A. ₹6,200 — Step 1: Use SI formula: SI = (P × R × T) / 100. Step 2: SI = (5000 × 8 × 3) / 100 = 120000 / 100 = ₹1,200. Step 3: Total Amount = Principal + SI = 5000 + 1200 = ₹6,200. So option A is correct.

Answer

B. ₹6,400

Answer

C. ₹6,100

Answer

D. ₹6,300

Question 2

At what rate of simple interest per annum will ₹8,000 amount to ₹9,600 in 2 years?

Accepted Answer

Correct answer: B. 10% — Step 1: Find SI = Amount - Principal = 9600 - 8000 = ₹1,600. Step 2: Use SI = (P × R × T) / 100, so 1600 = (8000 × R × 2) / 100. Step 3: 1600 = 160R, therefore R = 10%. So option B is correct.

Answer

A. 9%

Answer

C. 11%

Answer

D. 8%

Question 3

In how many years will ₹12,000 become ₹15,600 at 6% simple interest per annum?

Accepted Answer

Correct answer: B. 5 years — Step 1: Find SI = 15600 - 12000 = ₹3,600. Step 2: Use SI = (P × R × T) / 100, so 3600 = (12000 × 6 × T) / 100. Step 3: 3600 = 720T, therefore T = 5 years. So option B is correct.

Answer

A. 4.5 years

Answer

Answer

A. 10% p.a.

Answer

C. 12% p.a.

Answer

D. 13% p.a.

Question 6

In how many years will ₹3,600 amount to ₹4,392 at 11% simple interest per annum?

Accepted Answer

Correct answer: A. 2 years — Step 1: Interest = 4,392 - 3,600 = ₹792. Step 2: Using SI = (P × R × T) / 100, we get 792 = (3,600 × 11 × T) / 100. Step 3: 792 = 396T, so T = 2 years. Option A is correct.

Answer

B. 2.5 years

Answer

C. 3 years

Answer

D. 3.5 years
