Question

In a survey of 600 students in a school, 150 students were found to be taking tea and 225 taking coffee, 100 were taking both tea and coffee. Find how many students were taking neither tea nor coffee?

Answer 1

given that, `uu= 600`
lets take tea taking student be T and coffee be C
`T nn C = 100 `
only tea `150-100 = 50`
only coffee`25-100= 125`
let the student taking neither of the 2 drinks be x
now, `x+125+50+100 = 600`
`x+275 = 600`
`x=325`
