Question

simple interest at 13 1/2 per annum, amount =2502.50 after 4 yrs, find the sum

Answer 1

Let the P be 100

S.I = PTR/ 100
= 100×4×27/100×2
= ₹ 54

A = 100+54
A = ₹ 154

By unitary method,

if A is ₹154, then P is ₹100
if A is 2502.50 then P =

= 2502.50 × 100 / 154
Principal is ₹16,683.34
