Options

A. 400
B. 300
C. 350
D. 500

Explanation

To solve the problem step by step, we will use the unitary method.

### Step 1: Find the cost of one mango.
The cost of 30 mangoes is Rs. 150. To find the cost of one mango, we divide the total cost by the number of mangoes.

\[ \text{Cost of one mango} = \frac{\text{Total cost}}{\text{Number of mangoes}} = \frac{150}{30} = 5 \text{ Rs.} \]

### Step 2: Find the cost of 60 mangoes.
Now that we know the cost of one mango is Rs. 5, we can find the cost of 60 mangoes by multiplying the cost of one mango by 60.

\[ \text{Cost of 60 mangoes} = \text{Cost of one mango} \times \text{Number of mangoes} = 5 \times 60 = 300 \text{ Rs.} \]

### Final Answer:
The cost of 60 mangoes is Rs. 300.
