A shopkeeper sells one transistor for Rs. 840 at a gain of 20% and another for Rs. 960 at a loss of 4%. His total gain or loss percent is:

5\( {15\over 17}\)% loss

5\( {15\over 17}\)%gain

6\( {2 \ \over 3}\) %

None of these

Answer : Option B

Explanation :

C.P. of 1^st transistor = Rs.			\(\frac { 100 } { 120 }\)x 840		= Rs. 700.

C.P. of 2^nd transistor = Rs.			\(\frac { 100 } { 96 }\)x 960		= Rs. 1000

So, total C.P. = Rs. (700 + 1000) = Rs. 1700.

Total S.P. = Rs. (840 + 960) = Rs. 1800.

Gain % =			\(\frac { 100 } { 1700 }\)x 100	%			5 \(\frac { 15 } { 17 }\)%
