Profit and Loss

14.

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	% loss
	17

5	15	% gain
	17

6	2	% gain
	3

None of these

Answer: Option

Explanation:

C.P. of 1^st transistor = Rs.		100	x 840		= Rs. 700.
		120

C.P. of 2^nd 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

Why not A? Here it is asking both gain or loss right?

Sanjay said: 7 years ago

@Satish.

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

c.p. = s.p/profict%+c.p.%

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

What is the gain% formula? Please tell me.

Cathy said: 8 years ago

How can we say here loss is incurred?

Satish said: 8 years ago

How can 5.88 can be converted to 5 * 15/17?

Satya said: 8 years ago

Let cost price = x;
Case1:sp=840,profit=20%
x=840-0.2x;
1.2x=840;
x=700.

case2: sp= 960,loss=4%
x=960+0.04x;
0.96x=960;
x=1000.

Total cp=700+1000=1700; Total sp=840+960=1800;
1800-1700 = 100(Gain)
Gain% = (100/1700) * 100 gives the answer.

Can we solve this using alligation?

@Priya,

Let we assume 100 if the base cost price is not given.
