Answer» Answer: 50% Cost PRICE = RS. 480 Repair cost =20% of Rs. 480 = 100 20 ×480= Rs. 96 ∴Total cost = C.P. + Repair cost ⇒ Rs. 480+ Rs. 96= Rs. 576 NET PROFIT = Rs. 144 ∴ S.P. = Total cost + Net profit ⇒ Rs. 576+ Rs. 144= Rs. 720 Profit = S.P. − C.P. =720−480= Rs. 240 Now profit %= = 480 240 × 100=50%

Answer»

Answer:

50%

Cost PRICE = RS. 480

Repair cost =20% of Rs. 480 =

100

×480= Rs. 96

∴Total cost = C.P. + Repair cost

⇒ Rs. 480+ Rs. 96= Rs. 576

NET PROFIT = Rs. 144

∴ S.P. = Total cost + Net profit

⇒ Rs. 576+ Rs. 144= Rs. 720

Profit = S.P. − C.P.

=720−480= Rs. 240

Now profit %= =

480

240

× 100=50%
