Question

7.
Vinay bought a pizza and cut it into three pieces. When
he weighed the first piece he found that 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 three pieces weigh?​

Answer 1

Answer:

Let the three pieces of pizzabe x,y,z.

y−x=7

x−z=4

Now, according to question, we have

x+y+z=300

⇒4+z+7+x+z=300

⇒4+z+7+4+z+z=300

⇒3z+15=300

⇒3z=285

⇒z=

3

285

=95

∴ the lightest pizza weighs z=95g
