Question

OUT OF 75 PLAYERS WHO PLAY EITHER ONE OF THE GAMES , 40 PLAY CHESS , 50 PLAY CAROM, . FIND HOW MANY PLAY ONLY ONE GAME​

Answer 1

IN THE QUESTION THEY SAID THAT 75 PLAYERS PLAY BOTH THE GAME

SO THERE ARE 75 PLAYERS IN TOTAL

NOW TOTAL PLAYING = 40+50=90

THAT MEANS PEOPLE WHO PLAY BOTH THE GAME ARE 90-75=25

25 PLAYERS PLAY BOTH THE GAME

SO PLAYERS WHO PLAY ONE GAME =  75-25=50

SO 50 PLAYERS PLAY BOTH GAMES
