      (c) Neither gain or loss

      (d) Loss of 15 percent

       (e) None of these

Ans: (e) None of these

Explanation: Q.1.

 
C.P. = Rs.5600

 S.P. = Rs.5600x ¾ = Rs.4200

 Loss = Rs.5600-4200 = Rs.1400

 Loss percentage = 1400x100/5600 = 25%.Ans.

      (c) Rs.5,900

      (d) Rs.6,925

      (e) None of these

Ans: (e) None of these

Explanation: Q.2.

 
123% of CP =SP

 Therefore, CP = Rs.7,011x100/123 = Rs.5700. Ans.

Q.3. The cost price of 16 articles is the same as the selling price of 12 articles. Find the loss/profit percentages.

(a) 30%   (b) 32.50%  (c) 331/3%  (d) 40%  (e)None of these

Ans: (c) 331/3%.

Explanation. Q.3.

Q.4. Raju purchased an item for Rs.4,500 and sold it at the gain of 15%. From that amount he purchased another item and sold it  at the loss of 10%. What is his overall gain/loss?

(d) neither gain nor loss  (e) None of these

Ans: (b) Gain of Rs.157.50

Explanation Q.4.

1^st SP = Rs.4500 + 15% of 4500 = Rs.4500+Rs.675 = Rs.5175

2^nd CP = Rs.5175.

2^nd SP = Rs.5175 – 10% of 5175 = Rs.4657.50

Overall gain = Rs.4657.50 – 4500 = Rs.157.50. Ans.

Q.5. A shopkeeper labeled the price of his articles so as to earn a profit of 30% on the cost price. He then sold the articles by offering a discount of 10% on the labeled price. What is the actual percent profit earned in the deal?

(a) 18%  (b)15%  (c)20%   (d)Cannot be determined (e)None of these

Ans: (e) None of these

Explanation Q.5.

Let the CP of the article = Rs.100.

Then labeled price = Rs.130.

SP   = Rs.130- 10% of 130 = Rs.130-13 = Rs.117.

Gain = Rs.117 – Rs.100 = Rs.17.

Therefore, gain/profit percent = 17%. Ans.

Q.6. Profit earned by an organization is distributed among officers and clerks in the ratio of 5:3 respectively. If the number of officers is 45 and the number of clerks is 80 and the amount received by each officer is Rs.25,000/-, what was the total amount of profit earned?

(a)Rs.22 lakhs   (b)Rs.18.25 lakhs  (c)Rs.18 lakhs  (d)Rs.23.25 lakhs  (e) None of these

Ans: (c) Rs.18 lakhs.

Explanation  Q.6.

The total amount distributed among 45 officers = Rs.45x25000 = Rs.1125000.

Let the amount distributed to 80 clerks be ‘x’.

Then   1125000/x = 5/3, therefore, x = Rs.675000.

Therfore, the Total profit = Rs.1125000 + 675000 = Rs.18 lakhs. Ans.

Q.7. The cost of 8 gel pens and 12 ball pens is Rs.82. What would be the cost of 36 gel pens and 54 ball pens?

Q.8. A merchant sells his two cars – one at 15% loss and another at 12% profit. If the cost prices of the two cars are in the ratio of 1:2, what is his percent profit or loss?

(a)3% profit    (b)2% loss  (c)2% profit   (d)1.2%loss   (e)None of these

Ans: (a)3%  profit

Explanation Q.8.

Given that CPs are in the ratio 1:2

Therefore let the CPs be Rs.100 & Rs.200 respectively,

1^st SP = 100-15% of 100 = Rs.86.

2^nd SP = 200 + 12% of 200 = Rs.224.

Total CP = Rs.300.  Total SP = 85+224 = Rs.309.

Profit = Rs.309-300 = Rs.9.

Profit percent = 9x100/300 = 3% profit. Ans.

Q.9. The profit earned after selling an article for Rs.675 is twice the loss incurred after selling the article for Rs.435. What is the cost price of the article?

(a)Rs.450  (b)Rs.595  (c)Rs.400  (d)Rs.450   (e)None of these

Ans:(e) None of these

Explanation Q.9.

Let ‘x’ be the CP of the article.

i.e. Rs.675-x = 2(x-435)

675-x = 2x-870

675+870 = 3x, therefore, x=1545/3  =Rs.515. Ans.

Q.10. Mohan purchased 15 kgs of rice at the rate of Rs.26 per kg and 8 kgs of pulses at the rate of Rs.26 per kg. Whaat is the total amount that he paid to the shopkeeper?

Ans:(a) Rs.598.

Explanation Q.10.

Price of 15 kgs of rice at Rs.26/kg = 15x26 = Rs.390

Price of 8 kgs of pulses at Rs.26/kg = 8x26 = Rs.208

Therefore, Total amount = Rs.390+Rs.208 = Rs.598.Ans.

Q.11. Suhas sold an item for Rs.7500 and incurred a loss of 25%. At what price, should he have sold the item to have gained a profit of 25%?

 (d)Cannot be determined  (e) None of these

Ans: (b)Rs.12500.

Explanation Q.11.

255 loss means that Rs.7500 is 75% of CP.

Therefore, CP = 7500x100/75 = Rs.10000.

25% of Rs.10000 = Rs.2500.

To get a gain of 25%, the SP should be = Rs.10000+2500 = Rs.12500. Ans.
