Detailed Solution

Given that, Mrs Soni bought 7 1 2 litres of milk and out of which, 5 3 4 litres were consumed.
Let the litres of milk Mrs Soni bought and the litres of milk consumed in terms of fractions be 7 1 2 ,5 3 4 .
To make the subtraction process easier, converting given fractions to like fractions,
7 1 2 5 3 4 = 15 2 23 4 15 2 × 2 2 = 30 4 23 4 × 1 1 = 23 4 So, the difference between the fractions is,
7 1 2 5 3 4 = 30 4 23 4 7 1 2 5 3 4 = 7 4 7 4 =1 3 4
Therefore, the milk left with Mrs. Soni is 1 3 4 litres.
Hence, option (2) is correct.
