________________________________

$\large \frak \red{ \underline{Given :-}}$

• One-third of the tank can hold 80 litres of water.

$\large \frak \pink{ \underline{To \: Find :-}}$

• Quantity of the water that half of the tank holds is ?

$\large \frak \purple{ \underline{Solution :-}}$

Let consider the quantity of water that half of the tank can hold as 'x'

$\large \sf \dashrightarrow{ \dfrac{1}{3} \: of \: x \: = 80 \tiny{(litres)}}$

$\sf{Capacity \: of \: whole \: tank \: = 80 \times 3} \\ \sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \red{ = 240 \: litres}}$

Now,

$\large \sf{ \dfrac{240}{2}}$

$\large \sf{ \cancel\dfrac{240}{2}} \: = \red{120 \: litres}$

Henceforth, Quantity of water that half of the tank holds is 120 litres.
