Question

simple interest on a certain sum is 16 upon 25 of the sum the rate percent and time if both are equal​

Answer 1

Let sum = x. Then, S.I = `(16x)/25`

Let rate = R % and time = R years.

`:. (x xx R xx R)/(100)`

`= (16x)/25 or R^2 = (1600)/25 R = 40/5 = 8`

:. Rate = 8% and Time = 8 years.
