Question

A sum of money becomes 13.824

times of itself in 30 years then in how

many years it was 2.4 times of itself?​

Answer 1

Answer:

Let principal be 100

100 becomes 100*13.824=1382.4 in 30 years

interest in 30 years=1382.4–100=1282.4

Rate on interest=interest*100/Principal*30=1282.4*100/100*30=42.745 or 42.75%

100 to be 2.4 times=2.4*100=240

Interest=240–100=140

Number of years to earn interest of 140=Interest*100/Principal*42.75=140*100/100*42.75=3.275 years
