Answer 1

Answer:

Let x be the total number of members in the club. As per the given information, Venn diagram is drawn and shown in figure.

Total number of members x is calculated as follows:

x = members playing only Badminton + members playing only lawn tennis + memebers playing both + memebers playing none of the games

x = [ (2/5)x-120 ] + [ (3/4)x-120 ]+120 +30(1)

Solving the above eqn.(1) for x, we get x = 600

Hence total number of members = 600
