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

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)
