Read the given information carefully and answer the following questions.
Swimming, Skating and Taekwondo are three of the activities in a sports complex. Of the 1500 players in the complex, 15% are not involved in any of the three activities; 290 are involved in only Swimming; and 150 are involved in all the three activities. The number of players involved in only Taekwondo is 80% of the number of players involved in all the three activities; 815 players are involved in Skating; 70 players are involved in only Taekwondo and Skating; and 245 players are involved in only Swimming and Skating.
Number of players involved in all three activities is how much less than the number of players involved in only Swimming?
This question did not require detailed analysis and making the venn-diagram.
The questions asks the difference between the number of players involved in only swimming and the number of players involved in all three activities.

Players involved in only swimming: 290
Number of players involved in all three activities: 150
There are 140 less players doing all three activities than players doing only swimming.
Hence, Option C is the correct answer,
