S = 200
S \ (A U B) = 75

so A U B = 125
and ( A n B) = 40

A U B = A \ B + B \ A + (A n B)
125 = 170/3 + 85/3 + 40

so A would be 170/3 + 40

it doesn't look right, does it?

x + 2x + 40 = 125

x = 55
2x = 110

2x+x+40 = 200 - 75

or 3x = 125-40 = 85

Hence A = 2*85/3 +40 = 170/3 +40

Number of people in fraction !!!!
