Question

At how much rate a sum becomes doubles in
16 yr?
25/4 ​

Answer 1

Answer:

find how many times will it be in 8 years .

Suppose we have any sum of Money say 100.

Question says sum becomes double in 16 years ie 100 will become (100+100)=200.

Therefore it increases 100% in 16 year Eg.If I deposite $100 in bank then according to question,I would get $200( $100 which i deposited and $100 extra as interest) .

So if it increase 100% in 16 year then in 8 years it would increase 50%.

If i deposite $100 in 8 yrs I would get 50% extra on 100 ie (100+50=150).

So 1.50 or One and half times is the answer for this problem .
