Answer 2

Let the total no. of people = x
Then the people who joined mountaineering = x-45
Given, that 25% of the total people joined mountaineering
Therefore, x- 45 = 25/100 × x
100 (x-45) = 25x (cross multiplication )
100x - 4500 = 25 x
75 x = 4500
x = 60
Thus, the total number of people in the group are 60 and those who joined mountaineering are 15.
