A farmer bought toffees at 6 for a rupee. How many for a rupee must he sell to gain 20% ?

A. 7

B. 6

C. 5

D. 2

Answer : C. 5

Explanation:

Cost Price(C.P) of 6 toffees = Re. 1
Selling Price(S.P) of 6 toffees = 120% of Re. 1
= Rs. 6/5
For Rs. 6/5 toffees sold = 6.
For Re. 1, toffees sold = 6 x 5/6
= 5.

A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. His profit percent is ?

A. No profit, no loss

B. 5%

C. 8%

D. 10%

Answer : B. 5%

Explanation:

Cost Price (C.P) of 56 kg rice = Rs. (26 x 20 + 30 x 36)
= Rs. (520 + 1080)
= Rs. 1600.

Selling Price (S.P) of 56 kg rice = Rs. (56 x 30)

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 ?

A. 30%

B.70%

C. 100%

D. 250%

Answer : B .70%

Explanation:

Let Cost Price (C.P) = Rs. 100.

Then, Profit = Rs. 320, Selling Price (S.P) = Rs. 420.

New Cost Price (C.P) = 125% of Rs. 100 = Rs. 125

New Selling Price (S.P) = Rs. 420.

Profit = Rs. (420 – 125) = Rs. 295.

Required Percentage = ( (295/420) x 100 )%

= 70% (approximately).

A. 447%

B. 5511%

C. 10 %

D. 12 %

Answer : B . 5511%

A storekeeper sold a wrist watch for $660, including a sales tax of 10%. If the cost price of the watch is $500, what is the percentage profit for shopkeeper ?

A. 25%

B. 15%

C. 10%

D. 20%

Answer : D. 20%

Explanation:

$660 = Selling Price + Sales Tax (110%)
Actual selling price without including sales tax = 100 / 110 * $660 = $600
Cost Price = $500
Profit = Selling Price – Cost Price
= $600 – $500
= $100
Therefore profit percentage = Profit / Cost Price
= (100 / 500 ) * 100%
= 20%.

A. $120

B. $190

C. $192

D. $240

Answer : C.

Explanation:

Amount spent on the purchase of materials = 3/5 of the total amount = 3/5 * 600 = $360
Remaining amount = $ (600 – 360) = $240
Amount spent on travelling = 1/5 of the remaining amount = 1/5 * 240 = $48
Total amount spent = $ (360 + 48) = $408

A dishonest dealer professes to sell his goods at Cost Price but still gets 20% profit by using a false weight. What weight does he substitute for a kilogram ?

A. 855 1/2 grams

B. 833 1/3 grams

C. 833 1/2 grams

D. 875 2/7 grams

Answer : B. 833 1/3 grams

Explanation:

Let the error is x gm. So we have
( error / True weight – error ) * 100 = %gain profit
= ( x / 1000 – x ) * 100 = 20
x / 1000 – x = 1 / 5
5x = 1000 – x
6x = 1000
x = 1000/6 gm

Hence the weight = 1000 – (1000 / 6)
833 1/3

A watch was sold at a loss of 10%. If it was sold for Rs.140 more, there would have been a gain of 4%. What is the cost price ?

A. Rs 1000

B. Rs 1140

C. Rs 860

D. Rs 760

Answer : A. Rs 1000

Explanation:

Let the cost price of the watch be x.
It was sold for 10% loss that is 90x/100

If it was sold for 140 more, the price would be 90x/100 + 140 and this would be 4% gain which is 104x/100

So, 104x/100 = 90x/100 + 140
Multiply through by 100, we have
104x =90x + 14000
Subtract 90x from both sides, we have
14x = 14000
Divide both sides by 14, we have
x = 1000
So, the cost price is 1000

A sells a camera to B at profit of 20% and B sells it to C at a profit of 25%. If C pays Rs 450, what price did A pay for the camera ?

A . Rs 300

B . Rs 350

C . Rs 400

D . Rs 450

Answer : A . Rs 300

Explanation:

Let cost price for A = Rs. 100.
SP for A = CP for B = 100 + 20% of 100 = 120.
SP for B = CP for C = 120 + 25% of 120 = 150.

Given,
CP for C = 450
So,
150 = 450
1 = 450/150
100 = (450 *100)/150 = Rs. 300.
CP for A = Rs. 300.

On selling an article for Rs 1020, a merchant loses 15%. For how much price should he sell the article to gain 12% on it ?

A . Rs 1344

B . RS 1400

C . Rs 1200

D . RS 1500

Answer : A . Rs 1344

Explanation:

Selling Price (S.P) = Rs 1050
Loss = 15%
Let Cost Price (C.P) = 100%
SP = CP – Loss% = 100% – 15% = 85%

85% = Rs 1020
Therefore Cost Price = 100% = 1020/85 x 100 = 1200

To get 12% gain => SP = CP + Profit %
= 100 % + 12 %
= 112 %
= 1200 / 100 x 112 = Rs 1344
