उत्तर
Let the carpenter worked for x h.
Given, labour charge = ₹ 200 per hour
Then, total labour charge = ₹ 200x
As, amount charged by carpenter for making a bed
= Cost of materials + Total labour charge
∴ 2500 = 1100 + 200x
⇒ 200x = 2500 – 1100
⇒ 200x = 1400
⇒ x = `1400/200` = 7
Hence, the carpenter worked for 7 h.
