Answer 1

Answer:

29 kg

Step-by-step explanation:

Weight of 6 children = 25.5x6=153 Kg

Weight of 7 children = 26x7=182 Kg

So, if we subtract the average weight of 7 children from the average weight of 6 children we get the weight of the 7th chile.

weight of 7th child= 26x7 - 25.5x6

                                = 182-153

                                 = 29 Kg
