s= selling price
c = cost price
p = profit

p = s - c

(a) p=20%s,
s-c= .20s
0.8s = c, no information is given about c. INSUF.
(b) s = c + 50, no information of C INSUF.

FOR C
c + 50 - c = 0.20s
.2s = 50
s = 250

Ans. C

I give no new technique. Sorry!

Profit = SP - CP

(1)

Profit = 0.20SP

=> CP = 0.80SP

Not Sufficient

(2)

50 = SP - CP

Not Sufficient

(1) + (2)

0.20SP = 50

=> SP = 250

Answer - C

It's C.

(1) The merchant's gross profit on the appliance was 20% of the price at which the merchant sold the appliance.

Let p = profit
Let x = original cost of the appliance to the merchant

p = x + .2x

This alone won't give us the original price. #1 is insufficient.


(2) The price at which the merchant sold the appliance was $50 more than the merchant's cost of the appliance.

Using the original variables...

p = x + 50

This alone won't do it. #2 is insufficient. However, comparing the two equations:

.2x = 50
x = 250
250 + 50 = 300

Answer: C.

Yes, {Gross Profit} = {Selling Price} - {Cost}

What was the price at which a merchant sold a certain appliance?

Question: {Selling Price}=?

(1) The merchant's gross profit on the appliance was 20 percent of the price at which the merchant sold the appliance --> {Selling Price} - {Cost} = 0.2*{Selling Price} --> 0.8*{Selling Price} = {Cost}. One equation two unknowns. Not sufficient.

(2) The price at which the merchant sold the appliance was $50 more than the merchant's cost of the appliance --> {Cost} +$50 = {Selling Price}. One equation two unknowns. Not sufficient.

(1)+(2) We have that 0.8*{Selling Price} = {Cost} and {Cost} +$50 = {Selling Price}. So, we have two distinct linear equations with two unknowns, hence we can solve for each. Sufficient.

Answer: C.

Hope it's clear.

Okay thanks. What about "profit" is that the same as gross profit in terms of calculation?

solution:

...........................cost......................................................................sell
st(1)................... x .................................................................. 120%x insufficient
st(2)................... p ....................................................................... p+5 insufficient
using both, p × 120% = p+5
or, p = 25 .
So Answer (C)

SP = P + Purchase Price (PP)

Combined we have

SP = X
Profit = 50 = 0.2X

So SP = 250
Hence C
