a+b=10........eq1 a+c=20.........eq2 b+c=24.........eq3 Combine eq2 and eq3 Therefore ba=4.......eq4 Now, combine eq1 and eq4 Therefore 2b = 14 b=7 a=3 c=17 Combine weight 7+3+17=27kg.......lobatan!

Let D = Weight of the dog, C = Weight of the cat, and R = Weight of the rabbit Let X = their combined weight. Required: X = D + C + R Solution: We are given the following: C + R = 10..............(1) C + D = 24..............(2) D + R = 20..............(3) From (1) we have the following: C = 10  R..............(4) Substituting (4) in (2) we have: (10  R) + D = 24 ===>> D  R = 24  10 ===>> D  R = 14...........(5) Solving (3) and (5) simultaneously, we have the following: D + R = 20.............(2) D  R = 14.............(3) Adding (2) and (3) we will have: (D + D) + (R  R) = (20 +14) ====>> 2D = 34 Dividing through by 2 we have: D = 17...............(6) Substitute for D in (2) we have: 17 + R = 20 ===>> R = 20  17 Hence, R = 3........(7) Substituting for R in (1) we have: C + 3 = 10 ===>> C = 10 3 = 7.........( Given that the combined weight is thus: X = D + C + R We have from (6), (7) and ( the following: X = 17 + 7 + 3 ===>> X = 27 Therefore their combined weight is 27 kg 1 Like

What this maths question also show is Nairalanders can lie!. So, because someone answered correctly, everybody now get the same answer?. No single wrong answer?. If a Nairalander tell you to COME you'd better RUN.

No need for long calculations. Simply add up the weights (10+20+24) That's 54kg (made up of 2 cats, two dogs and two rabbits) 54/2 = 27kg (1cat, 1dog and 1 rabbit) 5 Likes

I did a simple figure 1,2,3 added together gives 54kg = combined weight of 2 rabbits + 2 cats + 2 dogs. Divided by 2 gives 27kg as answered by the algeraens.
