please answer it with approach ​

Answer 1

let total no of employees be x

3/5 of employees are males

no of males =3/5x

=> no of females = 2/5x

2/3rd of males linked the mobile number

No of males linked the mobile number

= 2/3 × 3/5x

=2/5x

60 females didn't link the mobile number

no of females linked the mobile number= 2/5x-60

total employees linked mob number=420

2/5x +2/5x -60 = 420

4/5 x =480

x/5= 120

x=600
