Answer:

Encik Arif's mass is 63kg

Step-by-step explanation:

Let Encik Arif's mass be x

the ratio of Encik Arif's mass to his son's mass is 3:2

That's

[tex] \frac{3}{2} [/tex]

The son's mass is 42, so the ratio of Encik Arif's mass to his son's is

x : 42

That's

[tex] \frac{x}{42} [/tex]

Now equate the two fractions

That's

[tex] \frac{3}{2} = \frac{x}{42} [/tex]

Cross multiply

3(42) = 2x

126 = 2x

Divide both sides by 2

We have the final answer as

x = 63

Hope this helps you
