Options

B. Rs 152
C. Rs 144
D. Rs 156

Answer

To solve the problem, we need to find the total cost of `1(1)/(2)` dozen tables and `1(1)/(2)` dozen chairs.

### Step-by-Step Solution:

1. **Understand the Quantity of Tables and Chairs**:
- `1(1)/(2)` dozen means 1.5 dozen.
- 1 dozen = 12 items.
- Therefore, `1(1)/(2)` dozen = 1.5 * 12 = 18 items.
- So, we have 18 tables and 18 chairs.

2. **Determine the Cost of Tables**:
- The cost of one table is Rs 5.
- Therefore, the total cost for 18 tables = Number of tables × Cost per table
- Total cost for tables = 18 × 5 = Rs 90.

3. **Determine the Cost of Chairs**:
- The cost of one chair is Rs 3.
- Therefore, the total cost for 18 chairs = Number of chairs × Cost per chair
- Total cost for chairs = 18 × 3 = Rs 54.

4. **Calculate the Total Cost**:
- Total cost = Total cost for tables + Total cost for chairs
- Total cost = Rs 90 + Rs 54 = Rs 144.

### Final Answer:
The total cost of `1(1)/(2)` dozen tables and `1(1)/(2)` dozen chairs is Rs 144.
