If the selling price of a mat is five times the discount offered and if the percentage of discount is equal to the percentage profit, find the ratio of the discount offered to the cost price.

A.

6:31

B.

11:30

C.

7:30

D.

31:6

Answer with explanation

Answer: Option CExplanation

Since S.P. = 5 (M.P. – S.P.) => 5 M.P. = 6 S.P.

M.P. = (6/5) S.P.

Since the percentage discount = Percentage profit,

65S.P − S.P65S.P×100 = S.P −C.PC.P×10065S.P – S.P65S.P×100 = S.P -C.PC.P×100

Therefore, 1/6 = (S.P/C.P) – 1 => S.P = (7/6) C.P

M.P = 6/5 S.P = 6/5 x 7/6 C.P = 7/5 C.P

Therefore, Ratio of discount to C.P

= (M.P – S.P)/C.P = [{(7/5)C.P – (7/6)C.P} / C.P.]

= 7/30

Therefore, the ratio is 7 : 30

A shopkeeper fixes the marked price of an item 35% above its cost price. The percentage of discount allowed to gain 8% is

A.

18%

B.

20%

C.

22%

D.

24%

Answer with explanation

Answer: Option BExplanation

Let the cost price = Rs 100

then, Marked price = Rs 135

Required gain = 8%,

So Selling price = Rs 108

Discount = 135 – 108 = 27

Discount% = (27/135)*100 = 20%

A man buys an item at Rs. 1200 and sells it at the loss of 20 percent. Then what is the selling price of that item

A.

Rs. 660

B.

Rs. 760

C.

Rs. 860

D.

Rs. 960

Answer with explanation

Answer: Option DExplanation

Here always remember, when ever x% loss,

it means S.P. = (100 – x)% of C.P

when ever x% profit,

it means S.P. = (100 + x)% of C.P

So here will be (100 – x)% of C.P.

= 80% of 1200

= (80/100) * 1200

= 960

By mixing two qualities of pulses in the ratio 2: 3 and selling the mixture at the rate of Rs 22 per kilogram, a shopkeeper makes a profit of 10 %. If the cost of the smaller quantity be Rs 14 per kg, the cost per kg of the larger quantity is:

A.

Rs 23

B.

Rs 25

C.

Rs 24

D.

Nonof these

Answer with explanation

Answer: Option CExplanation

Cost Price of 5 kg = Rs.(14*2 + x*3) = (28 + 3x).

Sell price of 5 kg = Rs. (22×5) = Rs. 110.

[{110 – (28 + 3x)}/(28 + 3x) ]* 100 =10

[82-3x/28 + 3x]= 1 / 10

820 – 30x = 28 +3x

33x = 792

x = 24

Ajay bought 15 kg of dal at the rate of Rs 14.50 per kg and 10 kg at the rate of Rs 13 per kg. He mixed the two and sold the mixture at the rate of Rs 15 per kg. What was his total gain in this transaction?

A.

Rs 1.10

B.

Rs 11

C.

Rs 16.50

D.

Rs 27.50

Answer with explanation

Answer: Option DExplanation

Cost price of 25 kg = Rs. (15 x 14.50 + 10 x 13) = Rs. 347.50.

Sell price of 25 kg = Rs. (25 x 15) = Rs. 375.

profit = Rs. (375 — 347.50) = Rs. 27.50.

The profit earned by selling an article for Rs. 832 is equal to the loss incurred when the same article is sold for Rs. 448. What should be the sale price for making 50% profit ?

A.

Rs. 660

B.

Rs. 560

C.

Rs. 1060

D.

Rs. 960

Answer with explanation

Answer: Option DExplanation

Let C.P. = Rs. C.

Then, 832 – C = C – 448

2C = 1280 => C = 640

Required S.P. = 150% of Rs. 640 = 150/100 x 640 = Rs. 960.

Bhajan Singh purchased 120 reams of paper at Rs 80 per ream. He spent Rs 280 on transportation, paid octroi at the rate of 40 paise per ream and paid Rs 72 to the coolie. If he wants to have a gain of 8 %, what must be the selling price per ream?

A.

90

B.

89

C.

D.

Answer with explanation

Answer: Option AExplanation

Total investment = Rs. (120 * 80 + 280 + (40/100) * 120 + 72).

= Rs. (9600 + 280+48 + 72) = Rs, 10000.

Sell price of 120 reams = 108% of Rs. 10000 = Rs. 10800.

Sell Price per ream = Rs. [10800/120] = Rs. 90.
