Answer:
answer to 1st question :
body mass of each children = m-30 kg
answer to 2nd question :
body mass of each children = (156+30n)/(1+n) kg
Step-by-step explanation:
body mass of the man = m kg
he is 30kg heavier than each of his children
so, body mass of each children = m-30 kg
answer to 1st question :
body mass of each children = m-30 kg
let number of each child = n kg
given,
mass of the father and children sum up to 156kg
=> m + (m-30)×n = 156
=> m + mn - 30n = 156
=> m(1+n) = 156 + 30n
=> m = (156+30n)/(1+n)
answer to 2nd question :
body mass of each children = (156+30n)/(1+n) kg
