Question

Josephine bought 8 packets of biscuits. Each packet had a mass of 500 g. She repacked them into 3 boxes. The first box was twice as heavy as the second box. The third box was 60 g heavier than the second box. What was the mass of the second box?

Answer 1

1313.3g is the weight of second box

Answer 2

Answer-

Mass of the second box is 985 g.

Solution-

Josephine bought 8 packets of biscuits and each packet had a mass of 500 g

So total mass of the biscuit is 8×500 = 4000 g

Let's assume the amount of biscuit in the second box is x

The first box was twice as heavy as the second box so, the amount of biscuit in the first box will be 2x

The third box was 60 g heavier than the second box, so the amount of biscuit in the third box will be x+60

Total amount of biscuits = 2x+x+x+60 = 4x+60

Then,

$\Rightarrow 4x+60=4000$

$\Rightarrow 4x=3940$

$\Rightarrow x=985$

Therefore, mass of the second box is 985 g.
