Answer

To solve the problem step by step, we need to find the amount when Rs. 5000 is invested at the same rate of interest for 30 months, given that Rs. 12000 becomes Rs. 15000 in 18 months at simple interest.

### Step 1: Calculate the Simple Interest from Rs. 12000 to Rs. 15000

1. **Identify the principal (P)**: Rs. 12000
2. **Identify the amount (A)**: Rs. 15000
3. **Calculate the interest (I)**:
\[ I = A - P = 15000 - 12000 = 3000 \]
