If 216 girls and 45 boys have tasted the samples, then the remaining samples will be enough for how many boys?

Answer 1

Answer:

1.38

2.255

Step-by-step explanation:

1.man can do work in=1/6

women can do work in=1/8

boy can do work in =1/24

let's take no of boys be x

x/24+1/6+2/8=2

LCM is 24

(x+4+6)/24=2

x+10=48

x=38

so 38 boys are required

2. there are total of 300 samples for boys and 45 have already tested so the remaining will be 255
