Question

Puan Hamidah bought satay from a stall for her children. Her eldest and youngest children ate 1/6 and 0.25 of all the satay respectively. The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay. How many sticks of satay did her eldest child eat?​

Answer 1

12.01 sticks of satay

Explanation:

Let

Total satay bought = x

Eldest child ate = 1/6x

Youngest child ate = 0.25x

Total = 1/6x + 0.25x

= 0.167x + 0.25x

= 0.417x

Remaining satay = x - 0.417x

= 0.583x

The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay.

Her and her other two children = 3 people

Sticks of satay pee person = 14

Total sticks eaten by 3 people = 14 × 3

= 42 sticks

0.583x = 42

x = 42/0.583

= 72.04

x = 72.04 sticks

Total satay bought = x = 72.04 sticks

Eldest child ate = 1/6x

= 1/6 * 72.04

= 12.01 sticks of satay
