Question

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:

1st piece- 99 grams

2nd piece- 106 grams

3rd piece- 95 grams

Step-by-step explanation:

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

y−x=7  ---(1)

x−z=4  ---(2)

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=  95

∴  z=95g

Now, substitute 'z' value in eqn//--(2)

We get, x=99 grams

then substitute 'x' value in eqn//--(1)

we get, y=106 grams
