Answer:

Let the Average Height of the 25 students be- x

Let the sum of heights of the 25 students be- a

Let the height of the boy who went out be- b

according to the question- (a/25)=x

I.e. a = 25x…… (1)

Now based on the switching of the 2 students

(a-b+165)/25= x+2

I.e. a-b+165=25x+50

a-b+115=25x

25x-b+115=25x. …… refer (1)

b=115 cms

Hence the height of the boy who went out is 115 cms.
