Question 1

24 bag of sugar weigh 21 kg. Howbags will weigh - 122kg ?

Question 2

If 24 bags of sugar weigh 21kg i.e

$24\text{ bags}\Rightarrow21\operatorname{kg}$

Let n bags of sugar weigh 122kg i.e

$n\text{ bags}\Rightarrow122\operatorname{kg}$

Relating the expressions

$\begin{gathered} 24\text{ bags}\Rightarrow21\operatorname{kg} \\ n\text{ bags}\Rightarrow122\operatorname{kg} \\ \text{Crossmultiply} \\ 24*122=21* n \\ 21n=2928 \\ \text{Divide both sides by 21} \\ (21n)/(21)=(2928)/(21) \\ n=139(3)/(7)\text{ bags} \end{gathered}$

Hence, the number of bags, n, is

$n=139(3)/(7)\text{ bags}$
