Question

If $3$ bags contain $120$ $kg$ of wheat$,$ find how much wheat can be contained in $20$ bags$.$

Answer 1

Step $1:$ To find the quantity of wheat in $20$ bags

It is given that $3$ bags contain wheat $=$$120kg$

Step $2:$ Now find the quantity of wheat in one bag using unitary method.

In $1$ bag the quantity of wheat $=\frac{120}{3}$ $kg$

$=40$ $kg$

Now quantity of wheat in $20$ bags $=20\times 40$

$=800$ $kg$

Hence, $20$ bags contain $800$ $kg$ of wheat
