Difficult Math Problem #92 - Sets

Problem Solving

Total No of people= 260

No. of people who purchased A+B+C+D+E =
61+88+56+75+60 = 340

So atleast 340-260 = 80 people would have bought more than 1 stock.

But to buy both B and D it would have to 75 people.

Im sorry answer = 75 people

PS: Hotel rooms

Problem Solving

================
Single bedrooms = 1400*15/60 = 350 hrs
Double bedrooms = 420 * 20/60 = 140 hrs

Total time = 490hrs

1person can work 7hrs
70 people can finish the job in 490hrs.

So Answer:70 people?
