The avg weight of 20 people is 60.when we replace a man with 50kg by an another man. The avg changes to 61.then what is the weight of the man?​

Answer»

ong>Answer:

So the sum of weights of people here is 8(x + 2.5) = 8x + 20 ... These all VALUES are replaced in the formula, then we get the answer "85". ... means may be new person weight will be greater than other remaining 7 PERSONS. ... new person weight=weight of person tht left+total MEN*AVERAGE INCREASED after ... x = Change in avg.
