Verified Answer
Ramu mixes 2 litres of mineral water costing Rs. 15 per litre with 18 ...
The 2 litres given to Shamu contain milk and water in the ratio 9:1, i.e., 1.8 litres of milk and 0.2 litres of water.

The remaining 18 litres contains 16.2 litres of milk and 1.8 litres of water.

After adding tap water, the ratio of milk to water becomes 9:10. ⇒ the quantity of tap water is 16.2 x 10/9 = 18 litres.

Since the mixture already has 18 litres, the total quantity now becomes 36 litres.

The total revenue is 36 x 50 + 2 x 50 (already sold) = 1900.

The total cost is 900 + (2 x 15) = Rs. 930.

Thus, his profit is 1900 – 930 = Rs. 970 ⇒ (970/930) x 100 = 104%.

Problem:

Ramu mixes 2 litres of mineral water costing Rs. 15 per litre with 18 litres of milk that he bought for Rs. 900. After selling 2 litres of this mixture to Shamu, Ramu adds tap water so that the ratio of milk to tap water is 9:10. If tap water is free and Ramu claims to sell at cost, what is his profit? Explain in detail.

Solution:

To find Ramu's profit, we need to calculate the cost of the mixture sold to Shamu and compare it with the cost of the ingredients used.

Calculating the cost of the mixture sold to Shamu:
- Ramu mixed 2 litres of mineral water with 18 litres of milk, resulting in a total of 20 litres of mixture.
- The cost of 2 litres of mineral water is 2 * Rs. 15 = Rs. 30.
- The cost of 18 litres of milk is Rs. 900.
- Therefore, the total cost of the mixture sold to Shamu is Rs. 30 + Rs. 900 = Rs. 930.

Calculating the cost of the ingredients used:
- Ramu bought 18 litres of milk for Rs. 900, so the cost of 1 litre of milk is Rs. 900 / 18 = Rs. 50.
- Ramu added 2 litres of mineral water, which costs Rs. 15 per litre, so the cost of 2 litres of mineral water is Rs. 2 * Rs. 15 = Rs. 30.
- Therefore, the total cost of the ingredients used is Rs. 900 + Rs. 30 = Rs. 930.

Comparing the cost of the mixture sold to Shamu with the cost of the ingredients used:
- The cost of the mixture sold to Shamu is Rs. 930.
- The cost of the ingredients used is also Rs. 930.
- Since the cost of the mixture sold is equal to the cost of the ingredients used, Ramu claims to sell at cost.
- Therefore, Ramu's profit is zero.

Conclusion:

Ramu does not make any profit from selling the mixture to Shamu as he claims to sell at cost.
