Question

There are 34 sweets in 1 kg. How many sweets will be there in 15 kg? If 17 sweets can be packed in 1 box, how many boxes are needed to pack all these sweets?

Answer 1

Number of sweets in 1 kg = 34
=> Number of sweets in 15 kg = 34 $\times$ 15

$34$
$\underset{–}{\times 12}$
$68$
$\underset{–}{340}$
$408$

So, there will be 408 sweets in total.

Number of sweets packed in 1 box = 17
So, to calculate the number of boxes needed, we need to divide 408 by 17.

$$\begin{array}{c}24\\ 17408\\ -\underset{–}{34}2\\ 68\\ -\underset{–}{68}\\ 0\end{array}$$ Thus, we need 24 boxes to pack all these sweets.
