Question

Vinay brought a pizza and cut it into three pieces. When he weighed the first piece he found it was 7g lighter than the second piece and 4g heavier than the third piece. If the whole pizza weighed 300g. How much did each of the pieces weigh?

Answer 1

Let $1^{st}$ piece be $x$.

Then, $2^{nd}$ piece $=x+7$ & $3^{rd}$ piece $=x-4$

According to the question,

$x+x+7+x-4=300$

$3x+3=300$

$3x=297$

$x=99$

Therefore,

$1^{st}$ piece $=99gm$ , $2^{nd}$ piece $=106gm$ & $3^{rd}$ piece $=95gm$

Hence, this is the answer.
