A. 4

B. 5

C. 9

D. 6

**Answer: C)**

**5. Choose the alternative which is closely resembles the mirror image of the given combination.**

**6. A number, when divided successively by 4, 5 and 6, leaves remainders 2, 3 and 4 respectively. The least such number is**

A. 250

B. 253

C. 190

D. 214

**Answer: D)**

**Solution:**

**7. The ratio of the sum of two numbers and their difference is 5 : 1. The ratio of the greater number to the smaller number is**

A. 2 : 3

B. 3 : 2

C. 5 : 1

D. 1 : 5

**Answer: B)**

**Solution:**

(x
+ y)/(x – y) = 5/1

=>
x + y = 5x – 5y => 4x = 6y

=>
x/y = 3/2

**8. If the sum of two numbers be multiplied by each number separately, the product so obtained are 247 and 114. The sum of the numbers is**

A. 19

B. 20

C. 21

D. 23

**Answer: A)**

**Solution:**

Let
the two numbers be x and y. Then ATQ,

(x
+ y) * x = 247 and (x + y) * y = 114

Then,
HCF of this numbers will be the value of (x + y) i.e 19

19
* x = 247 => x = 13

Similarly,
19 * y = 114 => y = 6

And
value of (x + y) = 19

**9. If x 8 y = (x + 3)^2 (y – 1), then the value of 5 * 4 is**

a) 192

b) 182

c) 180

d) 172

**Answer: A)**

**Solution:**

Given,
x * y = (x + 3)^2 (y – 1)

Therefore,
5 * 4 = (5 + 3)^2 * (4 – 1) = 64 * 3 = 192

**10. The product of two numbers is 2028 and their H.C.F. is 13. The number of such pairs is**

A. 1

B. 2

C. 3

D. 4

**Answer: B)**

**Solution:**

Let
the numbers be 13x and 13y.

ATQ,
13x * 13y = 2028 => xy = 12

Coprime
pairs of 12 = (1, 12) and (3, 4)

**11. How many bits does an IP address contain?**

A. 64 bits

B. 32 Bits

C. 128 Bits

D. 256 Bits
