First, find the sum of their ratios i.e. 5 + 3 + 2 = 10
The first person received
of the total number of mangoes; the second person received
of the total, and the last person received
The person with the smallest ration is the person who received
Now, we're asked to find the total number of mangoes shared.
Let's call it m.
If the person who received
of m received 25 mangoes, that means,
of m = 25
x m = 25
2m=250 (cross multiply)
(dividing through by 2)
m = 125
There is a total of 125 mangoes.
You can check
of 125 = 25
of 125 = 37.5
of 125 = 62.5
62.5 + 37.5 + 25 = 125
