**==================================**

**SOLUTION** -

Given,

**mean of 12 people salary** = Tk. 14, 500

**one more person salary** = Tk. 18, 400

To find out,**what is t****he total mean of 13 people?**

**mean of 12 employees' (monthly salary)** = Tk. 14, 500

**Mean = Sum / Number**

so,**Sum = Number * Mean**

**sum of 12 employees' (monthly salary)** = Tk. (14, 500 × 12 )

= Tk. 174, 000

**sum**** of 13 employees' (monthly salary)** = Tk. ( 174, 000 + 18, 400 )

= Tk. 192, 400

∴**net/new mean** = Tk. ( )

= Tk. 14, 800**(****ans****.)**
