Answer 1

The answer is here dude.

the total employees are = 500

employees are divided into 4 categories

first, category = 20

second category = 90

third category = 170

fourth category = 220

ratio of the employees = 1:2:3:4

equation = X +2X+3X+4X = 500

10X = 500

500/10

50

1X = 50

2X = 100

3X = 150

4X = 200

in the question the observations are wrong
