Question

10kg 20kg 24kg ?kg plz answer this for me

Answer 1

27KG

Explanation:

Mouse- M , Cat - C, Dog - D

M + C = 10 ----- (1)

M + D = 20 -------(2)

C + D = 24 --------(3)

(1) - (2) => C - D = -10 ---- (4)

(3) + (4) => 2C = 14

=> C = 7

Substitute C in (1) => M + 7 = 10

=> M = 3

Substitute M in (2) => 3 + D = 20

=> D = 17

Therefore C + M + D = 7 + 3 + 17 = 27KG
