Question

A sum becomes rs.1,352 in 2 years at 4% per annum compound interest. The sum is:

Answer 1

let the sum be x Rs.

therefore, 1352= x (1+4/100)^2

1352=x (1+1/25)^2

1352=×(26/25)^2

x=1352×25×25/26×26

x=Rs.1250

Hope this will help you ☺

Answer 2

let the principal be p.

time =2 year

rate = 4% p.a.

amount = x (1+4/100)^2

1352 = x(100+4/100)^2

1352 =x × 104/100 × 104/100

1352. = x × 26/25×26/25

1352. =676x/625

676x/625 = 1352

x = 1352×625/676

x= 1250
