A school has 54 students studying Physics, Chemistry and Biology. 33 study Physics, 25 Chemistry and 26 Biology. 10 study Physics and Chemistry, 9 study Biology and Chemistry while 8 study both Physics and Biology. Equal numbers study all three subjects as those who learn none of the three. how many students are taking all the three subjects?
(33 - 10 - 8 - x) + 10 + (25 - 10 - 9 - x) + 9 + (26 - 8 - 9 - x) + 8 + x + x = 54 (15 - x) + 10 + (6 - x) + 9 + (9 - x) + 8 + 2x = 54 x = 3
(33 - 10 - 8 - x) + 10 + (25 - 10 - 9 - x) + 9 + (26 - 8 - 9 - x) + 8 + x + x = 54
(15 - x) + 10 + (6 - x) + 9 + (9 - x) + 8 + 2x = 54
x = 3
