$\sf \blue { \underline { \sf ✯Given :- }}$

• Masud weighs 70.5kg
• The weight of his sister and father is 0.3 times and 1.5 of his weight respectively.

$\sf \blue { \underline { \sf ✯To \: find :- }}$

• The sum of the weight of his sister and his father.

$\sf \blue { \underline { \sf ✯Solution :- }}$

• Here, we know that his sister weighs 0.3 times of his weight.

$\sf \therefore \: \: His \: sister's \: weight \: = 0.3 \times 70.5kg \\ \sf \: = \frac{3}{10} \times \frac{705}{10} \\ \bf = \frac{2115}{100} = {\boxed{\bf 21.15kg}}$

And,

• His father's weighs 1.5 of his weight.

$\bf \therefore \: His \: father's \: weight \: = 1.5 \times 70.5 \\ \tt = \frac{15}{10} \times \frac{705}{10} \\ \tt = \frac{10575}{100} ={\boxed{\bf 105.75kg}}$
