Let the number of apples Mr Leon buy
Given the number of pears was 1/3 the
apples.
The number of pears = 1/3x.
Given the number of apples was twice the number of
Mangoes.
Number of mangoes = x/2.
Mr Leon spent $60 on some apples, mangoes and
pears in the ratio 3:5:2.
It means he spent $3y on apples, $5y on mangoes
and $2y on pears .
=> $3y + $5y + $2y = $60
=> $10y = $60
=> y = 6
He spend $18 on apples, $30 on mangoes
and $12 on pears.
Given mangoes were of 3 for $5
In $30 he can by 6*3=18 mangoes.
It means the number of mangoes he bought = 18.
Since, the number of mangoes = x/2
=> x/2 = 18 => x = 36
It means the number of apples he bought = 36
The number of pears he bought = 36/3 = 12
The total number of fruit he bought = 18 + 36 + 12
= 66.
He bought 66 fruits altogether.
