Question -

If a box of sweets is divided among 24 children, they will get 5 sweets each. How many would each get, if the number of the children is decreased by 4?



Answer -


Number of children

Number of Sweets

24

5

(24 – 4) or 20

a
We observe that on increasing the number of children, number of sweets got by each will be less. So, they are in inverse proportion.

x1y1 = x2y2
where x1 = 24, y1 = 5, x2 = 20
and y2 = a(let)
24 × 5 = 20 × a
a = 6
Hence, the required number of sweets = 6.
