Answer 1

Let us convert the mixed fraction to improper fraction :-

$10 \frac{1}{4} = \: \frac{41}{4} \\ \\ 25 \frac{3}{4} = \frac{103}{4} \\ \\ 16 \frac{1}{12} = \frac{193}{12}$

Lcm of the denominators is 12 so,

$\frac{41}{4} + \frac{103}{4} + \frac{193}{12} \\ \\ \\ = \frac{123 + 309 + 193}{12} \\ \\ = \frac{625}{12} \\ \\ = 52 \frac{1}{12} \\ \\ = all \: total \: he \: had \: rupees \: 52 \frac{1}{12}$
