Explanation

Let the price of the chair be =x

Let the price of table =400+x

6 of each sold at 4800

⟹6×(400+x)+6×x=4800

⟹x=200 

chair price =200 , table price =600

required percentage =600200​×100

                                    =3331​%

Explanation

Basic rate per hour = Re. (20/40) = Re. 1/2.

Overtime per hour = 125 % of Re. 1/2 = Re.5/8.

He worked x hours overtime.

Then 20 + 5/8 x = 25 (or) = 5/8 x = 5

X = 40/5 = 8 hours

=> he worked in all for (40 + 8) = 48 hours.

Explanation
