Answer 2

Answer:

R1: R2 : R3  ::: 4 : 9 : 16

Step-by-step explanation:

Let say Amount deposited are

P  , 2P  &  3P

& Rate of interest are R1  , R2  & R3

SI = 2S  , 9S  & 24S

2S = P * R1 * 1 /100

=> R1 = 200S/P

9S = 2P * R2 * 1 /100

=> R2 = 450S/P

24S = 3P * R3 * 1 /100

=> R3 = 800S/P

R1:R2 : R3  ::: 200S/P : 450S/P : 800S/P

=> R1:R2 : R3  ::: 20 : 45 : 80

=> R1:R2 : R3  ::: 4 : 9 : 16
