The CI on the same sum is Rs 2110

Step-by-step explanation:

The CI on a sum in 8 year is Rs 400

Compound Interest, CI = Rs 400

Principal, P = p

Time, t = 8 years

Rate of interest, r = r

The CI on same sum in 16 years is Rs 1300

Compound Interest, CI = Rs 1300

Principal, P = p

Time, t = 16 years

Rate of interest, r = r

 ----------------- (2)

Divide eq(2) by eq(1)

Solve for r

Put r in equation 1

Put P = 320, r = 0.1067, t = 20 into CI formula
