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

I chose E.


P = s-c
1) p = 0.20s Insufficient
2) p = 50 Insufficient

For Both: 0.20s =50
Ans. 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

(1) + (2)

0.20SP = 50

=> SP = 250

Answer - C


pushpitkc hello

Hey dave13

I'm sure you must be aware of the following definitions but am writing them anyway
SP = CP + Profit -> Profit = SP - CP

Now, coming back to the question

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

(1) The merchant's gross profit on the appliance was 20 percent of the price at which the merchant sold the appliance.
(2) The price at which the merchant sold the appliance was $50 more than the merchant's cost of the appliance.


1. Profit was 20% of SP (or) Profit = 0.2*SP
This can be written as 0.2*SP = SP - CP -> CP = 0.8*SP
We can't arrive at an unique price at which the appliance was sold(Stmt 1 alone is insufficient)

2. SP = CP + 50(for every unique cost price, the selling price will wary - no unique price)
Now, statement 2 is also insufficient!

On combining the two statements,
we know that CP = 0.8*SP -> SP - 50 = 0.8*SP -> (1-0.8)SP = 50 -> SP = \(\frac{50}{0.2} = \frac{500}{2} = 250\)

Hope that helps you!
