SSC CGL - 02 Dec 2022 - Shift 3 • Quantitative Aptitude • Q71

What annual instalment will discharge a debit of Rs.5,664 in 4 years at 12% simple interest?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. Rs.1,200.

Given:

Amount = Rs 5,664

Time = 4 years

Rate = 12%

Formula used:

Installment = (100 × A)/{100 × T + RT(T – 1)/2}         ---- (1)

Where R = rate, A = amount and T = time

Calculation:

Using equation (1), we get

Installment = (100 × 5664)/(100 × 4 + 12 × 4 × 3/2)

⇒ (100 × 5664)/(400 +72)

⇒ 100 × (5664/472)

⇒ 100 × 12 = Rs 1200
