Question

The time in which Rs.72 becomes Rs.81at 25:4 p.a simple interest is

Answer 1

Given,

principal (p) = 72

Amount (A )= 81

simple interest (S. I ) = A - P

S.I = 81 - 72 = Rs. 9

S.I = Rs 9

given ,Rate (R) = 25 / 4 , let " T " is the time

T = S.I × 100 / R× P

T = 9 × 100 / 25 / 4 × 72

T = 900 / 25 × 18

T = 900 / 450

T = 2 years
