28. CRE 4 - Profit & Loss | Percentage, Profit & Loss

What percent profit is made by selling an article at a certain price if by selling it at half that price there would be a loss at 12.5%?

A.
50%
B.
37.5%
C.
60%
D.
75%

Answer: Option D

Explanation :

Let CP = Rs. x and SP = y

Then,

If SP_new = 0.5 y, Loss% = (x - 0.5y)/x = 0.125 or x – 0.5y = 0.125x

or 0.875 x = 0.5 y ⇒ y = 0.875/0.5 x = 1.75 x

But when, CP = x, SP = y, profit % = (y - x)/x × 100

= $\frac{1.75 x - x}{x} \times 100$ = $\frac{0.75 x}{x} \times 100$ = 75%

Hence, option (d).

Oranges are bought at 11 for a rupee and an equal number more at 9 for a rupee. If they are sold at 10 for a rupee what is the gain or loss percent?

A.
no loss, no gain
B.
10% loss
C.
1% loss
D.
5% gain

Answer: Option C

Explanation :

If x be the number of oranges at each of the prices, then,

Total purchase = x/11 + x/9 = (9x + 11x)/99 = 20x/99

Sales revenue = 2x/10 = x/5

% gain = $\frac{\frac{x}{5} - \frac{20 x}{99}}{\frac{20 x}{99}} \times 100$ = $\frac{\frac{99 x - 100 x}{495}}{\frac{20 x}{99}} \times 100$ = $\frac{- x}{495} \times \frac{99}{20 x} \times 100$ = -1 or 1% loss.

Hence, option (c).

A table was sold for Rs. 119 at a percentage of profit equal to the cost price of the table. The cost price of the table is :

A.
Rs. 49
B.
Rs. 100
C.
Rs. 70
D.
Rs. 89

Answer: Option C

Explanation :

Let CP be Rs. x.

Then, (119 - x)/x × 100 = x

⇒ x² = 11900 - 100x

⇒ x² + 100x - 11900 = 0

⇒ x = $\frac{- 100 \pm \sqrt{100^{2} + 4 \times 11900}}{2}$ = $\frac{- 100 + 240}{2}$ = Rs. 70

(-ve value has no meaning, hence discarded)

Hence, option (c).

A man who makes a profit of 25% by selling sugar at Rs. 4.25/kg., lowers his price so as to gain only 17 paise per kg., In what ratio must his sales be increased so that his total profit may be the same as before?

A.
1 : 6
B.
1 : 5
C.
1 : 4
D.
1 : 3

Answer: Option B

Explanation :

Let CP of sugar be Rs. x/kg.

Then, $\frac{4.25 - x}{x}$ = 0.25

⇒ 4.25 - x = 0.25x

⇒ 1.25x = 4.25

∴ x = 3.4

Old profit = 4.25 – 3.4 = 0.85

New Profit = 0.17

Hence, 0.85 : 0.17 :: old sales : new sales.

⇒ Hence, $\frac{o l d s a l e s}{n e w s a l e s} = \frac{1}{5}$

Hence, option (b).
