एक रेडियो का अंकित मूल्य Rs. 480 है एक दुकानदार 10% की छूट देकर 8% की लाभ कमाता है यदि कोई भी छूट ा दी जाए तो उसे कितना लाभ प्रतिशत होगा?A. 0.18B. 0.185C. 0.205D. 0.2

Answer» Correct Answer - D
Marked price = Rs. 480
Selling price after 10% discount (10% क)
`=Rs. 480xx(90)/(100)=Rs. 432`
Cost price
`=432xx(100)/(100+8%)=432xx(100)/(108)`
Rs. 400
If no discount then selling price
=Marked price = Rs. 480 gain percent
`=(480-400)/(400)xx100=(80)/(400)=20%`
Alternate
`therefore (100-D%)/(100+P%)=(CP)/(MP)`
`(CP)/(MP)=(100-10)/(100+8)=(90)/(108)=(5)/(6)`
If no discount then M.P =S.P
` therefore` CP=5, S.P=6 Gain%
`=(6-5)/(5)xx100`
`=(1)/(5)xx100=20%`
