What is the rate of interest per annum ?

I. The CI in 8 years is more than the amount.

II. The difference between SI and CI in 2 years is Rs.450

III. An amount double itself at SI in 15 years

Only I and II are sufficient

Only III is sufficient

Only II and III are sufficient

All are not sufficient

None

From III :
Principal = P, Amount = 2P
Interest = 2P – P = P
SI =P = P*R*15/100 => R = 15%

Hence, option 2 is the correct answer.
