A.2685

B.2636

C.2250

D.2675

E.2690

**Answer –** C.2250

**Explanation :**

CP = 100, SP (with tax) =120

New SP = 100 – 5 = 95

Discount = 120 – 95 = 25

Discount = 25/95 * 8550 = 2250

2. **Cost Price of two mobiles is the same. One is sold at a profit of 20% and the other for Rs. 5200 more than the first. If the net profit is 40%. Find the cost price of each mobile?**

4.** A reduction of 20% in the price of sugar enables a housewife to purchase 6 kg more for Rs. 240. What is the original price per kg of sugar?**

A. Rs.10 per Kg

B. Rs.8 per Kg

C. Rs.6 per Kg

D. Rs.5 per Kg

E. None of these

**Answer –** A. Rs.10 per Kg

**Explanation:**

Reduction in price = 1/5 = 20%

Increase in Quantity = 25%

25% = 6 Kg.

original amount of Sugar = 6*4 = 24Kg.

Original price of the sugar = 240/24 = Rs. 10 per kg.

5.** A Bike is available at 40% discount at showroom “A” and the same is available at only a 25% discount at showroom “B”.

Cost price (CP) = 40 % discount on MP = 0.6y = 60000

⇒ y= Rs.100000 MP

SP at Show Room “A” = Rs. 60000

SP at Show Room “B” = 100000 X 0.75 = 75000; Difference = 15000

6. **Arun can do a piece of work in 40 days, but Bala can do the same work in 5 days less, than Arun, when working alone. Arun and Bala both started the work together but Bala left after some days and Arun finished the remaining work in 30 days with half of his efficiency but he did the work with Bala with his complete efficiency. For how many days they had worked together?**

A. 25/3 days

B. 31/3 days

C. 35/3 days

D. 38/3 days

E. None of these

**Answer –** C. 35/3 days

**Explanation :**

1 day work of Arun and Bala = 1/40 + 1/35 = 15/280

Arun finished the remaining work in 30 days = 30 * 1/40 * 2 = 3/8

Remaining work was done by Arun and Bala = 5/8

Worked together = (5/8)/(15/280) = 35/3 days.

7. **Kiran can do a work in 20 days, while Karan can do the same work in 25 days. They started the work jointly. A few days later Suman also joined them and thus all of them completed the whole work in 10 days. All of them were paid total Rs.1000. What is the share of Suman?**

Remaining work was done by Suman = 10%.

Share of Suman = 10/100 * 1000 = 100

8.** 7 Indian and 4 American finish a job in 6 days. 7 African and 3 American finish the same job in 8 days. The efficiency of each person of a particular nationality is the same but different from others. One Indian One American and One African will complete the work in:**

A. 10 days

B. 12 days

C. 24 days

D. 36 days

E. None of these

**Answer –** C. 24 days

**Explanation :**

7I + 4Am = 1/6

7Af + 4Am = 1/8

7I + 7Af + 7Am = 7/24

1I + 1Af + 1Am = 1/24

Therefore, One Indian One American and One African will complete the work in – 24 days.

9.** Chitra is twice efficient as Arun. Bala takes thrice as many days as Chitra. Arun takes 12 days to finish the work alone. If they work in pairs(i.e Arun-Bala, Bala-Chitra, Chitra-Arun) starting with Arun – Bala on the first day, Bala – Chitra on the second day and Chitra – Arun on the third day and so on, then how many days are required to finish the work?**

A. 26/9 days

B. 46/9 days

C. 16/9 days

D. 56/9 days

E. None of these

**Answer –** B. 9 days

No of days taken by Arun = 12 days

No of days(Arun:Bala:Chitra) = 2:3:1

1 day work of (Arun+Bala) = 5/36

1 day work of (Bala+Chitra) = 8/36

1 day work of (Chitra+Arun) = 9/36

5 days of total work – 35/36

1/36 is done by Arun-Chitra

Number of days taken by Arun-Chitra for the rest of the work = (1/36)/(9/36) = 1/9

Total time taken to complete the work = 5 + 1/9 = 46/9 days

10.** Work is done by 30 workers not all of them have the same capacity to work. Every day exactly 2 workers, do the work with no pair of workers working together twice. Even after all possible pairs have worked once, all the workers together work for six more days to finish the work. Find the number of days in which all the workers together will finish the work?**

A. 22 days

B. 20 days

C. 24 days

D. 35 days

E. 32 days

**Answer –** D. 35 days

**Explanation :**

30 workers work in pairs, with no same pair of workers working together twice

29[1/w1 + 1/w2 ….. + 1/w30] + 6[1/w1 + 1/w2 ….. + 1/w30] = 1

[1/w1 + 1/w2 ….. + 1/w30] = 1/35

35 days.

E.None of these

**Answer –** D. 3200

**Explanation:**

Let there are X books in the library.

Hindi books = 60% of X = 60X /100 = 0.6X

Remaining Books = X – 0.6X = 0.4X

English books = 40% of reaming books = 60% of 0.4X = 0.24X.

Malayalam Books = X-0.6X -0.24X = 0.16X

Given,

0.24X = 4800

X = 4800/0.24 = 20000

Malayalam Books = 0.16X = 0.16*20000 = 3200.

**Explanation :**

SI =>Amount = x*8*7/100 + x = 56x+100x/100 = 156x/100 = 39x/25

CI=> 39x/25[(1+10/100)2 – 1] 1638 = 39x/25[121/100 – 1] = 39x/100[21/100] X = 1638*100*25/21*39 = 5000

40. **Rs.5200 was partly invested in Scheme A at 10% pa CI for 2 years and Partly invested in Scheme B at 10% pa SI for 4 years. Both the schemes earn equal interests. How much was invested in Scheme A ?**

A.Rs.1790

B.Rs.2200

C.Rs.3410

D.Rs.2670

E.None of these

**Answer –** C.Rs.3410

**Explanation :**

Amount invested in Scheme B = X

Amount invested in Scheme A = 5200 – x

X*10*4/100 = (5200-x)*21/100……………………[(1-10/100)2-1] = 21/100

40x/100 = (5200-x)*21/100

2x/5 = (5200-x)*21/100

200x = 5200*21*5 – x*5*21

200x = 546000 – 105x

305x = 546000

X = 1790

Scheme A = 5200 – 1790 = 3410

41. **An alloy contains iron, copper, and zinc in the ratio of 3:4:2. Another alloy contains copper, zinc, and tin in the ratio of 10:5:3. If equal quantities of both alloys are melted, then the weight of tin per kg in the new alloy**

a) 1/8 kg

b) 1/10 kg

c) 1/12 kg

d) 1/14 kg

e) None of these

**Answer –** c) 1/12 kg

**Explanation :**

I:C:Z = 3:4:2 (in first alloy) and C:Z:T = 10:5:3

Equal quantities are taken. So, I:C:Z = 6:8:4 in first alloy and C:Z:T = 10:5:3

I = 6

C = 8 + 10 = 18

Z = 4+5 = 9

T = 3

So weight of tin = 3/36 = 1/12

42.** 8 liters are drawn from a flask containing milk and then filled with water. The operation is performed 3 more times. The ratio of the quantity of milk left and the total solution is 81/625. How much milk the flask initially holds?**

a) 10ltr

b) 20ltr

c) 30ltr

d) 40ltr

e) None of these

**Answer –** b) 20ltr

**Explanation :**

let initial quantity be Q, and final quantity be F

F = Q*(1 – 8/Q)^4

81/625 = (1-8/Q)^4

3/5 = 1 – 8/Q

Q = 20

43.** A 40-liter mixture contains milk and water in the ratio of 3:2. 20 liters of the mixture is drawn off and filled with pure milk. This operation is repeated one more time. At the end what is the ratio of milk and water in the resulting mixture?**

a) 5:1

b) 6:1

c) 8:1

d) 9:1

e) None of these

**Answer –** d) 9:1

**Explanation :**

milk = 40*3/5 = 24 and water = 16 litres initially

milk = 24 – 20*3/5 + 20 = 32 – 20*4/5 + 20 = 36

water = 16 – 20*2/5 = 8 – 20*1/5 = 4

45.** There are 4 bananas, 7 apples and 6 mangoes in a fruit basket. In how many ways can a person make a selection of fruits from the basket.**

a) 269

b) 280

c) 279

d) 256

e) None of these

**Answer –** c) 279

**Explanation :**

Zero or more bananas can be selected in 4 + 1 = 5 ways (0 orange, 1 orange, 2 orange, 3 orange, and 4 orange) similarly, apples can be selected in 7 +1 = 8 ways and mangoes in 6 +1 = 7 ways

so total number of ways = 5*8*7 = 280

but we included a case of 0 orange, 0 apples, and 0 mangoes, so we have to subtract this, so 280 – 1 = 279 ways
