 If the compound interest on a certain sum at 1623%16\frac{2}{3}\%per annum for 2 years is ₹2600, find the simple interest on the same sum at the same rate and for the same period.

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. ₹2400.

R = 1623%16\frac{2}{3}\% = (50/3)%

CI = P[(1 + R/100)n - 1]

⇒ 2600 = P[(1 + 50/300)2 - 1]

⇒ 2600 = P[(7/6)2 - 1]

⇒ 2600 = P(49/36 - 1)

⇒ 2600 = P(13/36)

⇒ P = 2600 × 36/13 = 7200

SI = (P × R × T)/100 = (7200 × 50/3 × 2)/100 = 2400
