The diagram gives the percentage of 4500 residents of a Nashik township who use the gym, the pool and the library; the number outside uses none. How many residents use exactly one of these?

Question

Accepted Answer

2295. Exactly one = 21\% + 17\% + 13\% = 51\%, and 51% of 4500 is 2295. 2520 wrongly adds the 5% in the centre, 3600 is the 80% who use at least one, and 1080 is the 24% who use exactly two.
