Question

find the principal if the compound interest at the rate 10% per annum for three year is rs 331

Answer 1

Heya ✋

Let see your answer !!!!!

Given that

C.I. = ₹331

R = 10 % p.a.

T = 3 years

P = ?

Solution

C.I. = P[(1 + R/100)^n - 1]

=> 331 = P[(1 + 10/100)^3 - 1]

=> 331 = P[(100 + 10/100)^3 - 1]

=> 331 = P[(110/100)^3 - 1]

=> 331 = P[(11/10)^3 - 1]

=> 331 = P[1,331/1,000 - 1]

=> 331 = P[1,331 - 1,000/1,000]

=> 331 = 331P/1,000)

=> P = 331 × 1,000/331

=> P = ₹1,000
