A. 4
B. 5
C. 9
D. 6
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
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
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
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
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
Solution:
Let the numbers be 13x and 13y.
ATQ, 13x * 13y = 2028 => xy = 12
Coprime pairs of 12 = (1, 12) and (3, 4)
