Question

Out of $250$ mangoes in a basket $,$$\frac{3}{5}$of them are rotten and $\frac{1}{5}$of them are eaten $.$How many are left $?$

Answer 1

Step1:Find the number of mangoes left

Total number of mangoes $=$$250$

Number of rotten mangoes $=$$\frac{3}{5}$of $250$ $=$$\frac{3}{5}$$\times$$250$ $=$$\frac{3\times 250}{5}$ $=$$\frac{750}{5}$ $=$$150$

Number of mangoes eaten $=$$\frac{1}{5}$of $250$ $=$$\frac{1}{5}$$\times$$250$ $=$$\frac{1\times 250}{5}$ $=$$\frac{250}{5}$ $=$$50$

Number of mangoes left $=$Total number of mangoes $-$ Number of rotten mangoes $-$Number of mangoes eaten

$=$$250$$-$$150$$-$$50$

$=$$50$

Hence $,$ $50$ mangoes are left$.$
