From task we know that students with less than 3 years doesn't have intersection with business and more than three years
so more than 3 years only + business only + united business and more than 3 years + 60 (less than 3 years) = 200
more than 3 years only + business only = 140
more than 3 years + business = 120 + 70 = 190
intersect equal 190 - 140 = 50 students who have business and more than 3 years
Answer is B
