Answer 1

Answer:

5 years

Step-by-step explanation:

A sum of money becomes 6 times of itself at simple interest in 25 years

Interest in 25 years: sum+x=6*sum => x= 5*sum= 500%

• 500% interest in 25 years
• 500%/25= 20% interest in 1 year
• 100% interest will double the sum in: 100%/20= 5 years

So answer is 5 years to get the sum to double up
