Answer 2

Given :

• Weight of Raghvan = 72 kg
• Weight of his son = 75% of 72 kg

To Find :

• difference between their weights ?

Solution :

Let weight of his son be x

and we know that,

• weight of his son = 75% of 72 kg

$\bold{: \implies \: x = \cancel\frac{75}{100} \times 72} \\ \\ \bold{ : \implies x =0.75 \times 72 } \\ \\ \bold{ : \implies \boxed{ \bold{x = 54}}} \: \: \: \: \: \: \: \: \: \: \:$

so, weight of his son is 54 kg

now, we have to find diffference between their weights ;

➪ 72kg - 54kg

➪ 18 kg

hence, diffference between their weights is 18 kg
