Number of people who like cricket = 60% Number of people who like football = 30% Number of people who like other games = 100% – (60% + 30%) = 10% Now Number of people who like cricket = 60% of 50,00,000 = 60/100 x 50,00,000 = 30,00,000 And Number of people who like football = 30% of 50,00,000 = 30/1Read more
Number of people who like cricket = 60%
Number of people who like football = 30%
Number of people who like other games = 100% – (60% + 30%) = 10%
Now Number of people who like cricket = 60% of 50,00,000
= 60/100 x 50,00,000 = 30,00,000
And Number of people who like football = 30% of 50,00,000
