Question

Alice and Bernice have a total mass 108 kg altogether. If Alice is twice as heavy as Bernice, what is Alice's mass?

Answer 1

Step-by-step explanation:

Let, the mass of Bernice is x kg.

so, the mass of Alice will be 2x, according to the given condition.

As, the total mass of them is 108 kg.

so, x + 2x = 108

or, 3x = 108

or, x = 108/3

Now, x = 36 kg

So, the mass of Alice is (36 × 2) = 72 kg.
