Answer 2

Answer:

275 grams

Step-by-step explanation:

let the weight of pear be x,

let the weight of onion be y,

and let the weight of the mushroom be z.

Now, we are given,

1. x + z = 200
2. x + y = 240
3. y + z = 110
4. x + y + z = ?

Now, from equation 1, we get

⇒ z = 200 - x                      (equation 5)

And, from equation 2, we get

⇒ x + y = 240

⇒ y = 240 - x                      (equation 6)

Putting both the resulting equations in equation 3, we get

⇒ y + z = 110

⇒ (240 - x) + (200 - x) = 110

⇒ 240 - x + 200 - x = 110

⇒ 240 + 200 - x - x = 110

⇒ 440 - 2x = 110

⇒ 440 - 110 = 2x

⇒ 330 = 2x

⇒ 330 ÷ 2 = x

⇒ 165 = x

Now, if x = 165, then

⇒ y = 240 - x                           (from equation 6)

⇒ y = 240 - 165

⇒ y = 75

and

⇒ z = 200 - x                          (from equation 5)

⇒ z = 200 - 165

⇒ z = 35

Now, calculating equation 4,

⇒ x + y + z = ?

⇒ (165) + (75) + (35) = ?

⇒ x + y + z = 275
