Question

how many years will the sum of money double itself at 6% units per annum​

Answer 1

Heya mate here's your answer,

Principal (P)=x rupees

Amount (A)=2x rupees

Rate ( R)= 6%

Time (T)=?

Interest (I)=A-P

= 2x-x

= x rupees

Now,

T = I × 100÷P×R

= x × 100÷x × 6

=100x÷6x

= 16.6 years
