Rs 22300

Rs 24300

Rs 21300

Answer And Explanation

Answer: Option A

Explanation:

Let at Rs x it can earn 15% pr0fit

85:18700 = 115:x [as, loss = 100 -15, Profit = 100 +15]

x = (18700*115)/85

= Rs.25300

Ques. A man gains 20% by selling an article for a certain price. If he sells it at double the price, the percentage of profit will be.

130%

140%

150%

160%

Answer And Explanation

Answer: Option B

Explanation:

Let the C.P. = x,

Then S.P. = (120/100)x = 6x/5

New S.P. = 2(6x/5) = 12x/5

Profit = 12x/5 - x = 7x/5

Profit% = (Profit/C.P.) * 100

=> (7x/5) * (1/x) * 100 = 140 %

Ques. The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25% then determine the value of x.

Answer And Explanation

Answer: Option C

Explanation:

Let the cost price 1 article = Re 1

Cost price of x articles = x

S.P of x articles = 20

Gain = 20 -x

=>25=(((20−x)/x)∗100)

=>2000−100x=25x

=>x=16

In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit

70%

80%

90%

None of above

Answer And Explanation

Answer: Option A

Explanation:

Let C.P.= Rs. 100.

Then, Profit = Rs. 320,

S.P. = Rs. 420.

New C.P. = 125% of Rs. 100 = Rs. 125

New S.P. = Rs. 420.

Profit = Rs. (420 - 125) = Rs. 295

Required percentage = (295/420) * 100

= 70%(approx)

A man bought an article and sold it at a gain of 5 %. If he had bought it at 5% less and sold it for Re 1 less, he would have made a profit of 10%. The C.P. of the article was

Rs 100

Rs 150

Rs 200

Rs 250

Answer And Explanation

Answer: Option C

Explanation:

Let original Cost price is x

Its Selling price = 105/100 * x = 21x/20

New Cost price = 95/100 * x = 19x/20

New Selling price = 110/100 * 19x/20 = 209x/200

[(21x/20) - (209x/200)] = 1

=> x = 200
