Mr Leon spent $60 on some apples, mangoes and pears in the ratio 3:5:2. The number of apples was twice the number of mangoes. The number of pears was 1/3 the number of apples. The mangoes were at 3 for $5. How many fruits did he buy altogether?

3:5:2     of  60 dollars means    18 dollars on apples     30 dollars on mangoes     and 12 dollars on pears

 

if mangoes are 3 for 5 dollars ....that means 18 mangoes were purchases

  apples = 2 * mangoes = 36 apples

  pears = 1/3 apples = 12 pears                      Add them together for answer .......

amount spent on apples --- $ 3x
amount spent on mangoes -- $ 5x
amount spent on pears ---$ 2x
3x+5x+2x = 60
x = 6

"The mangoes were at 3 for $5", but he spent 5x or $30 on mangoes
at 3 for $5, there must have been 18 mangoes. 

number of
apples : pears : mangoes = 2y : 2y/3 : y 
= 6y : 2y : 3y

But we know the number of mangoes is 18
so 3y = 18, y = 6
so we have 36 apples, 12 pears and 18 mangoes

check:
twice as many apples as mangoes ?? Yes
The number of pears was 1/3 the number of apples ?? , YES

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.
