A store's selling price of $2,240 for a certain computer would yield a profit of 40 percent of the store's cost for the computer. What selling price would yield a profit of 50 percent of the computer's cost?
A) $2,400
B) $2,464
C) $2,650
D) $2,732
E) $2,800

CP = SP ( 100/100 + P%) => 2240(100/140) = 1600.

SP = CP (100 + P% / 100) => 1600(150/100) = 2400.

Option A is correct answer.

Nice Question.
Here CP=x=> x(1+40/100)=2240=> x=1600
now 50%x=> 800
profit 800
=> new SP = CP+P=2400

let c be the cost of the computer

1.4c = 2240
c = 1600

1.5c = 1600(1.5)
1.5c = 2400 (the price that would yield a 50% profit for the computer)

A store’s selling price of $2240 for a certain computer would yield a profit of 40 percent of the store’s cost for the computer. What selling price would yield a profit of 50 percent of the computer’s cost?

(A) $2400
(B) $2464
(C) $2650
(D) $2732
(E) $2800

Letting C = the store’s cost for the computer, we can create the equation:

2240 - C = 0.4C

2240 = 1.4C

1600 = C

So for a profit of 50%:

R - 1600 = 0.5 x 1600

R - 1600 = 800

R = 2400

Answer: A

SP = 2240 $
LET: THE CP = x

PROFIT% = SP-CP/CP * 100
40 = 2240-x/x * 100
on solving : x = 1600 = CP

NOW, 50 = SP-1600/1600 * 100
on solving : SP = 2400$ ... ans A

(A) $2400
(B) $2464
(C) $2650
(D) $2732
(E) $2800

One potential way to do this is to note $2240, the sales price, is basically 1.4 times the cost of the computer. In algebra, let's say that is 1.4c

We're asked then in a sense to figure out what 1.5c would be.

Let's first increase 1.4c and its equivalent dollar amount by 10%

1.40c + 0.14c = $2240 + $224
1.54c = $2464

Because we're looking for 1.5c, the answer has to be a bit lower than this dollar value.

The only one that could possibly work is (A)
