*Challenge yourself with the question before look out for the given solution‼!*

**Upper primary school mathematics question UPQ289**

Sarin, Hairu and Fatimah each had some stickers. Sarin and Hairu had 38 stickers in total. Hairu and Fatimah had 41 stickers in total. If Sarin and Fatimah together had 47 stickers, how many stickers did Sarin have?

Solution:

Draw the Math model

From the model

S + H – H – F + S + F = 38 – 41 + 47

S + S = 44

S = 22

The number of stickers Sarin had = 22

Alternative Solution:

By equations

Given:

S + H = 38

H + F = 41

S + F = 47

Solve the above three equations

F – H = 47 – 38 = 9

2F = 41 + 9 = 50

F = 25

S = 47 – 25 = 22

The number of stickers Sarin had = 22
