Rs.215

- First, let's find the rate of interest. Rs.72 amounts to Rs.104.4 in 3 years.

- Interest = Rs.104.4 - Rs.72 = Rs.32.4

- Simple Interest formula: \( I = PRT / 100 \)

- Rearrange to find rate: \( R = (I \times 100) / (P \times T) = (32.4 \times 100) / (72 \times 3) = 15\% \)

- Now apply this 15% interest rate for Rs.120 over 5 years.

- Interest = \( PRT / 100 = (120 \times 15 \times 5) / 100 = Rs.90 \)

- Total amount = Principal + Interest = Rs.120 + Rs.90 = Rs.210

- So, for Rs.120 in 5 years at the same rate, the amount is Rs.210.

- Option 3: Rs.210 is the correct answer.
