Answer should be data inadequate. Suppose principal is 100 and we take 5% interest, then after 6yrs it will be 130 and after 9 years it will be 145. Solving this gives 26/29 which is not equal to 2/3.

P and R is constant.
Then ratio = t1/t2.
Then ratio = t1/t2.

3:2 is correct. Not 2:3 because rate of interest is inversly proportional to time.

PTR/PTR.
PR6/PR9,
PR = 6/9,
PR = 2/3.
P:R = 2:3.
PR6/PR9,
PR = 6/9,
PR = 2/3.
P:R = 2:3.

@All.
I think there is No change in the rate of interest.
So, 6:9=2:3.

When the principal and rate of interest are constant, then Simple interest is directly proportional to time.
So, here the answer is 2:3.
So, here the answer is 2:3.
