Answer 2

➤ Answer :-

(a) 2:3:5

Total $=$ 2+3+5 $=$ 10

Percentage of 2 :-

$\dashrightarrow \tt \frac{2}{10} \times 100$

$\dashrightarrow \tt \cancel \frac{200}{10} = 20 \bf\%$

Percentage of 3 :-

$\dashrightarrow \tt \frac{3}{10} \times 100$

$\dashrightarrow \tt \cancel\frac{300}{10} = 30 \bf\%$

Percentage of 5 :-

$\dashrightarrow \tt \frac{5}{10} \times 100$

$\dashrightarrow \tt \cancel \frac{500}{10} = 50 \bf\%$

(b) 2:5:9

Total $=$ 2+5+9 $=$ 16

Percentage of 2 :-

$\dashrightarrow \tt \frac{2}{16} \times 100$

$\dashrightarrow \tt \cancel\frac{200}{16} = 12.5 \bf\%$

Percentage of 5 :-

$\dashrightarrow \tt \frac{5}{16} \times 100$

$\dashrightarrow \tt \cancel\frac{500}{16} = 31.25 \bf \%$

Percentage of 9 :-

$\dashrightarrow \tt \frac{9}{16} \times 100$

$\dashrightarrow \tt \cancel \frac{900}{16} = 56.25 \bf\%$
