Quantitative Aptitiude (CLAT) Percentage

80% of students of a class took Statistics and 45% took Mathematics. If each student took Statistics or Mathematics and 40 took both, the total number of students in the class was:

160

180

200

225

Explanation:

Use n(A U B) = n(A) + n(B) - n(A !''''! B)
so, 100% = 80% + 45% -40
= 125% -40
25% =40,
100% =160
