Arithmetic Ability:

Q1. The smallest among the numbers 2250, 3150, 5100 and 4200 is

a) 4200
b) 5100
c) 3150
d) 2250

ANS: b

Explanation:

2250, 3150, 5100 and 4200 can be written as :
2250 = ( 2 )5*50 = 3250
3150 = ( 3 )3*50 = 2750
5100 = ( 5 )2*50 = 2550
4200 = ( 4 )4*50 = 25650
Hence, the smallest number is 5100
So, Ans is option B.

Q2. If part of a journey takes 10 minutes, then to complete ( 3 / 5 )th of that journey, it will take

a) 40 minutes
b) 45 minutes
c) 48 minutes
d) 36 minutes

ANS: c

Explanation: part of journey means = 4 - 155/40 = 5/40th of the journey will take 10 mins
Hence, for the full journey it will take 80 mins
Therefore for 3/5 th of the journey,it will take = ( 3/5 ) * 80 = 48 mins
Hence, Ans is option C.

Q3. A reduction of 20% in the price of rice enables a customer to purchase 12.5 kg more for Rs. 800. The original price of rice per kg is

a) Rs. 14
b) Rs. 16/-
c) Rs. 12/-
d) Rs. 15/-

ANS: b

Explanation:

Let the price of rice is Rs x / kg
As per the question
800/ 0.8x - 800 / x = 12.5
160/0.8x = 12.5

Q4. If A:B = 3:4 and B:C = 6:5, then C:A is

a) 10:9
b) 9:10
c) 8:9
d) 9:8

ANS: a

Explanation:

A : B = 3 : 4 and B : C = 6 : 5,
Then C : A will be = A : B : C = 9 : 12 : 10
Hence, ratio of C : A = 10: 9.

Q5. When n is divided by 6, the remainder is 4. When 2n is divided by 6, the remainder is

a) 2
b) 0
c) 4
d) 1

ANS: a

Explanation:

When n is divided by 6, the remainder is 4. Hence,the number can be written as
n = 6k +4
hence, 2n = 12k + 8 and when 2n is divided by 6 : remainder will be ( 12 k + 8 ) / 6 = 2
So,12k gives remainder 0 with 6 and 8 gives remainder 2 with 6. So, remainder is 0 + 2 = 2.Hence, Ans is option A.

Q6. Let a = 1/(2 - sqrt 3) + 1/(3 - sqrt 8) + 1/(4 - sqrt 15). Then we have

a) a > 18
b) a >= 18
c) a = 18
d) a = 9

ANS: a

Explanation: Q7. The value of is 1/20 + 1/30 + 1/42 + 1/56 + 1/72 + 1/90 is

a) 1/10
b) 3/5
c) 3/20
d) 7/20

ANS: c

Explanation:

1/(4x5) + 1/(5x6) + 1/(6x7) + 1/(7x8) + 1/(8x9) + 1/(9x10)
= (1/4 - 1/5) + (1/5 - 1/6) + (1/6 - 1/7) + (1/7 - 1/8) + (1/8 - 1/9) + (1/9 - 1/10)
= 1/4 -1/10 = 3/20

Q8. The greatest of the following numbers 0.16, Sqrt 0.16, (0.16)2, 0.04 is

a) 0.16
b) Sqrt 0.16
c) 0.04
d) (0.16)2

ANS: b

Explanation:

Check Each Option
A => 0.16
B => 0.4
C => 0.04
D => (0.16)2 = 0.0256
Hence, the greatest number is 0.4
So, Ans is option B.

Q9. In two alloys A and B, the ratio of zinc to tin is 5 : 2 and 3 : 4 respectively. Seven kg of the alloy A and 21 kg of the alloy B are mixed together to form a new alloy. What will be the ratio of zinc and tin in the new alloy?

a) 2:1
b) 1:2
c) 2:3
d) 1:1

ANS: d

Explanation:

Alloy A : which weighted 7 kg has zinc & tin in ratio = 5 : 2 i.e Zinc in alloy A = 5 kg & tin in alloy A = 2kg
Alloy B : which weighted 21 kg has zinc & tin in ratio = 3 : 4 i.e Zinc in alloy A = 9 kg & tin in alloy A = 12kg
Hence, total Zinc : total tin = 14 : 14 = 1 : 1 So, answer is option D.

Q10. If a number is increased by 25% and the resulting number is decreased by 25%,then the percentage increase or decrease finally is

a) No change
b) Decreased by 6 1/4%
c) Increased by 6 1/4%
d) Increased by 6%

Ans: b

Explanation:

Let the number be 100.
So 100 + 25% = 125
125 - 25% = 93.75
So net change = 100 - 93.75 = 6.25%
