Question

Ruchi had 2 1/2 litres of milk. She used 1/2 litre for curd, 3/5 litre for tea, 1/4 litre for coffee, and the remaining she gave to her children in the breakfast. How much milk was used by the children for breakfast?

Answer 1

Answer: 1 15/100

Step-by-step explanation: 2 1/2- 1/2 = 2 - 3/4 = 1 3/4 - 3/5 = 1 15/100

Answer 2

Given parameters:

Total volume of milk Ruchi has =
`2(1)/(2)` liters

Amount used for curd =
`(1)/(2)` liters

Amount used for tea =
`(3)/(5)` liters

Amount used for coffee =
`(1)/(4)` liters

Unknown:

Quantity of milk used by the children for break fast = ?

Since this quantity is the remaining volume;

Remaining volume = Total volume - (Amount used for curd + amount used for tea + amount used for coffee)

Remaining volume =
`(5)/(2) - ((1)/(2) + (3)/(5) + (1)/(4) )`

Remaining volume =
`(23)/(20)`

The remaining volume used by the children is
`(23)/(20)`
