Answer 1

A) 48 Kg

B) 8 Kg

C) 40 Kg

Explanation:

If 30% of the mass is equal to 24 Kg.

Then 10% of the mass will be equal to 8 Kg. (Divide both values by 3).

You can now use this info to find the other values:

10 x 6 = 8 x 6, so 60% = 48 Kg.

10 x 1 = 8 x 1, so 10% = 8 Kg.

10 x 5 = 8 x 5, so 50% = 40 Kg.

A) 48 Kg

B) 8 Kg

C) 40 Kg
