In a Coimbatore college, 60% of students study Tamil, 50% study Hindi and 20% study both, as shown; the rest study neither. If 90 students study neither language, how many students are in the college?

Question

Accepted Answer

900. At least one language = 40 + 20 + 30 = 90\%, so neither = 10\%. 10% is 90 students, so the college has 900. 810 is the 90% who study a language, 1800 takes neither as 5%, and 300 takes it as 30%.
