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:
Answer: Option
Explanation:
| C.P. of 1st transistor = Rs. |  |
100 | x 840 |  |
= Rs. 700. |
| 120 |
| C.P. of 2nd transistor = Rs. | |
100 | x 960 | |
= Rs. 1000 |
| 96 |
So, total C.P. = Rs. (700 + 1000) = Rs. 1700.
Total S.P. = Rs. (840 + 960) = Rs. 1800.
 Gain % = |
|
100 | x 100 | % |
= 5 | 15 | % |
| 1700 | 17 |

Can some one tell me, why not these?
S.P 1 = 840.
Gain of 20% of 840 = 20/100*840 = 168.
Then C.P1 = S.P-Gain.
= 840-168 = 672.
S.P 1 = 840.
Gain of 20% of 840 = 20/100*840 = 168.
Then C.P1 = S.P-Gain.
= 840-168 = 672.

c.p. = s.p/profict%+c.p.%
Easy method find cost price.
C.P. % = 100 %.
So, 840/100+20 = 840/120 = 700.

So, 840/100+20 = 840/120 = 700.

Cp of trans1 = 100*840/120 = 700.
Cp of trans2 = 100*960/96 = 1000.
Gain = 400*100/1700 = 400/17.
Cp of trans2 = 100*960/96 = 1000.
Gain = 400*100/1700 = 400/17.

@Priya.
Gain = (S.P-C.P/C.P*100).
= (1800-1700/1700*100).
= (100/1700*100).
= (100/17).
Gain = (S.P-C.P/C.P*100).
= (1800-1700/1700*100).
= (100/1700*100).
= (100/17).

Remember if C.P is 100 then S.P is 120 (If 20% gain, if 4% loss then C.P is 100 S.P is 96).

20 % of 840 is 678.
Then 840-678 = 168 is the c.p.
How 700 is c.p? Please explain to me.
Then 840-678 = 168 is the c.p.
How 700 is c.p? Please explain to me.

Total sp is (840+960)=1800
cp=1700
gain=(sp-cp)=1800-1700=100
so gain%=(100/1700*100)
cp=1700
gain=(sp-cp)=1800-1700=100
so gain%=(100/1700*100)

At last in the gain formula, how can we take gain as 100? please can someone explain.

Yes, the right answer is 5.88.
How it come 5.15/17%?
Please explain me.

@Satish.
It is 100/17 so 17*5=85 and reminder is 5 and balance is 15.
