Answer 1

Given data :-

• In an office, average income of 20 employees is 3 3,200 per month.
• The average income of other 10 employees is * 3,500 per month.

Solution:-

→ Total income of 20 employees is

= {Average income of 20 employees} × 20

→ Total income of 20 employees is

= 33200 × 20

→ Total income of 20 employees is

= {unit} 664000 ....[1]

→ Total income of 10 employees is

= {Average income of 10 employees} × 10

→ Total income of 10 employees is

= 3500× 10

→ Total income of 10 employees is

= {unit} 35000 ....[2]

From [1] & [2]

→ Total income of 30 {20 with 10}employees = 664000 + 35000

→ Total income of 30 {20 with 10} employees = {unit} 699000 ....[3]

→ Average income of one employees

= {Total income of 30 employees}/30

→ Average income of one employees

= {699000}/30

→ Average income of one employees

= {unit} 23300

Hence, average in come one employees is {unit} 23300.
