Question

A boy spends 20% of his pocket money on oranges, one quarter of it on apples and 5% in paying fines,
what fractional part of the whole has he left?​

Answer 1

Answer:

let the pocket money be 100

pocket money spend on oranges= 20/100*100=20

pocket money spent on apple = 1 quarter= 25

pocket money spend on fees = 5/100*100=5

money left =20+25+5/100

= 50/100=1/2

hope it helps

Answer 2

Answer:

One half of the whole has been left by the boy

Step-by-step explanation:

Let the pocket money of the boy be 'x'

Given that he spends 20% on oranges.

=> Money spent on oranges = 20% of x

                                               = $\frac{20}{100}$ * x

                                               = x/5              --(i)

Given that he spends one quarter on apples.

We know that one quarter = $\frac{1}{4}$

=> Money spent on apples = $\frac{1}{4}$ of x

                                             = $\frac{1}{4}$ * x

                                             = x/4              --(ii)

Given that he spends 5% in paying fines.

=> Money spent on fines = 5% of x

                                          = $\frac{5}{100}$ * x

                                          = x/20              --(iii)

Therefore, the total amount spent = $\frac{x}{5}$ + $\frac{x}{4}$ + $\frac{x}{20}$

                                                         = $\frac{4x+5x+x}{20}$

                                                         = $\frac{10x}{20}$

                                                         = $\frac{x}{2}$

Therefore, the amount left = x -  $\frac{x}{2}$

                                             =  $\frac{x}{2}$

                                             = $\frac{1}{2}$ * x

Therefore, one half of the whole has been left by the boy
