Question

in what time will a sum double itself at the rate of 10% p.a. SI​

Answer 1

Answer:

Let the sum be 100. 100 +( 100 × N x 10/100) = 200, where N is the period in years. 100 + 10 N = 200. 10 N = 100. N = 10 . Sum

Answer 2

Step-by-step explanation:

Let the sum be 100.

100 +( 100 × N x 10/100) = 200, where N is the period in years.

100 + 10 N = 200.

10 N = 100.

N = 10 .

Sum doubles in 10 years
