Question

13.A tank contains 18 3/7 litres of water. Due to
leakage, 3/5 of the water gets wasted. How much
water is available for consumption?
​

Answer 1

$\large\star \: \: \underline{ \underline{ \red{given : }}}$

$\: \: \: \: \: \: \: \: \: \rightarrow \: water = 18 \large\frac{3}{7} = \frac{129}{7} \small l$

$\: \: \: \: \: \: \: \: \rightarrow \: leaked \: \: water = \large \frac{3}{5}$

$\pink{ \boxed{ \underline{ \purple{water \: left = total \: water - leaked \: water}}}}$

$\implies \: \large \frac{129}{7} - \frac{3}{5}$

$\implies \: \large\frac{645 - 21}{35}$

$\boxed{ \boxed{ \red{\: = \large\frac{624}{35} \: \: liters }} }$
