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

**Lower primary school mathematics question LPQ99**

Fatimah has three times as many stickers as Hairu. Sarin has 48 fewer stickers than Hairu. If the three of them have 372 stickers altogether, how many stickers does Sarin have?

Solution:

Draw the model,

Per the model,

5U = 372 + 48 = 420

1U = 84

Hairu has 84 stickers

The number of stickers Sarin has = 84 – 48 = 36

Alternative Solution:

Sarin’s stickers ==> 1U

Sarin has 48 fewer stickers than Hairu,

Hairu’s stickers ==> 1U + 48

Fatimah has 3 time more stickers than Hairu,

Fatimah’s stickers ==> 3U + 48 × 3 = 3U + 144

Given their total stickers = 372

Per the model,

5U = 372 – 48 × 4 = 180

1U = 36

The number of stickers Sarin has = 36
