Question

Weight of 25 copies is 5 kg find the weight of 30 copies

Answer 1

$\huge\mathbb{SOLUTION:-}$

$\bold{Given}\begin{cases}\sf{weight\:of\:25\:copies=5kg}\end{cases}$

• We have to find the cost of 30 copies

$\bf\underline{\purple{According\:To\: Question:-}}$

• Now first find the cost of 1 copy

$\sf\implies weight\:of\:25\: copies=5kg\\ \\ \sf\implies weight\:of\:1\:copy=\frac{\cancel5}{\cancel{25}}\\ \\ \sf\implies 1\:copy\: weight= \frac{1}{5}$

• Now the weight of 30 copies

$\sf\implies weight\:of\:30\: copies=\frac{1}{5}\times 30\\ \\ \sf\implies weight\:of\:30\: copies=\frac{1}{\cancel5}\times \cancel{30}\\ \\ \sf\implies 30\:of\: copies\: weight=6kg$

$\boxed{\sf{\purple{weight\:of\:30\: copies=6kg}}}$

Answer 2

$\underline \mathbb{SOLUTION}$

$\underline \mathbb{GIVEN:}$

》Weight of 25 copies = 5kg

$\underline \mathbb{TO\:FIND}$

》Weight of 30 copies.

$\underline \mathbb{ATQ}$

》We have to find weight of 1 copy.

$= > weight \: of \: 25copies = 5kg$

$\underline \mathbb{NOW}$

$= > weight \: of \: 1 \: copy = \frac{5}{25} kg$

$= > weight \: of \: 1 \: copy = \frac{1}{5} kg$

$\underline \mathbb{NOW}$

$= > weight \: of \: 30 \: copies = \frac{1}{5} \times 30$

$= > weight \: of \: 30 \: copies = 6kg$

$\underline \mathbb{HENCE}$

》WEIGHT OF 30 copies = 6 kg
