1.	A man sold two articles at Rs 375 each. On one he gains 25% and on the other he loses 25%. Howmuch does he gain or loss on the whole transaction? Also, find the gain per cent or loss per centon the whole transaction
Answer» SP = Rs. 375 if gain = 25%gain% = (SP-CP)/CP * 100⇒ 25 =(375-CP)/CP * 100⇒ 25/100 =(375-CP)/CP⇒ 0.25CP = 375 - CP⇒ 0.25CP + CP = 375⇒ CP = 375/1.25= Rs.300 if loss = 25%loss% = (CP-SP)/CP * 100⇒ 25 =(CP-375)/CP * 100⇒ 25/100 =(CP-375)/CP⇒ 0.25CP = CP - 375⇒ CP -0.25 CP = 375⇒ CP = 375/0.75= Rs.500 Total CP = 300+500 = 800Total SP = 375+375 = 750 loss = 800- 750 = Rs. 50loss% = loss/CP * 100 = 50/750 * 100 = 6.67%

Answer»

SP = Rs. 375

if gain = 25%gain% = (SP-CP)/CP * 100⇒ 25 =(375-CP)/CP * 100⇒ 25/100 =(375-CP)/CP⇒ 0.25CP = 375 - CP⇒ 0.25CP + CP = 375⇒ CP = 375/1.25= Rs.300

if loss = 25%loss% = (CP-SP)/CP * 100⇒ 25 =(CP-375)/CP * 100⇒ 25/100 =(CP-375)/CP⇒ 0.25CP = CP - 375⇒ CP -0.25 CP = 375⇒ CP = 375/0.75= Rs.500

Total CP = 300+500 = 800Total SP = 375+375 = 750

loss = 800- 750 = Rs. 50loss% = loss/CP * 100 = 50/750 * 100 = 6.67%
