mrrandomguy: The answer is 27kg Let C=Cat, R=Rat, and D=Dog. C+R=10kg..... (1) D+R=20kg..... (2) D+C=24kg..... (3) From 1, R=10-C. Them substitute in (2) D+10-C=20 D-C=10..... (4) From (3), make D subject of the formula. D=24-C. Substitute in (4) 24-C-C=10 -2C=-14 C=7 Substitute C=7 in (1) 7+R=10 R=3 Substitute R=3 in (2) D+3=20 D=17 Therefore, Cat is 7kg, rat is 3kg and the dog is 17kg. The total weight of the three is 27kg. 1 Like |
