IF weight of:
CAT + RAT = 10KG
DOG + RAT = 20 kg
DOG + CAT = 24 kg
so what will be
DOG+CAT+RAT=?
answer quickly plz........

Given that,  Weight  of -:
                                    CAT + RAT = 10kg  ---(1)
                                    DOG + RAT = 20kg ---(2)
                                    DOG + CAT = 24kg ---(3)
Now, adding equation (1), (2) and (3), we have
                                2(CAT + RAT + DOG) = (10 + 20 + 24)kg
                                 2(CAT + RAT +DOG) = 54kg
                                   CAT + RAT + DOG = 54kg/2 = 27kg
And, we got our answer as 27kg.
