Question

IN A CLASS OF 100 STUDENTS ,35 LIKE SCIENCE ,45 LIKE MATH , 10 LIKE BOTH. HOW MANY LIKE EITHER OF THEM , HOW MANY LIKE NEITHER OF THEM

Answer 1

Answer: 5 like either, 5 like neither.

Step-by-step explanation: If we add up those who like science, math and both, we get 90. That leaves 10 students, and because all the other numbers end in 5’s or 0’s, I’d say we split this evenly. So 5 like either, and 5 like neither.

Answer 2

Like either science or math but not both: 60

Like neither: 30

Explanation:

Total: 100

Like science: 35

Like math: 45

Like both: 10

Subtract 10 from "like science" and 10 from "like math"

Like only science: 25

Like only math: 35

Like both science and math: 10

Total who like math, science, or both: 70

Like either science or math but not both: 25 + 35 = 60

Like neither: 100 - 70 = 30
