Question

Three brothers are sharing a birthday cake equally amongst themselves. If the weight of one piece is 250 g, find the weight of the entire cake?

• A. 1050 g
• B. 600 g
• C. 450 g
• D. 750 g

Answer 1

The correct option is D 750 g

Since the cake is being equally divided amongst the 3 brothers, so each brother is eating $\frac{1}{3}$ of the cake.

If the weight of one piece is 250 grams, therefore, the weight of the entire cake would be three times the piece of one cake.

So, the total weight of the cake is
$3\times 250grams=750grams$

The total weight of the cake is $750grams$.
