3 4 = 703 704� = 210 704
5 2 = 425 422� = 210 422
7 3 = 307 303� = 210 103
Largest number = 210 1055 = 5 Ans.
3.(C) Let the digit at Ten's place = z
N = 100x + 10z + y
N – 100x – y = 10z
N – 100x – y is divisible by 10.
4.(A) m = n2 – n
m = n (n – 1)
m2 – 2m = m(m – 2)
= n (n – 1) × (n2 – n – 2)
= n(n – 1) (n – 2) × (n + 1)
Now, for n = 3
m2 – 2m = (3 – 1) (3 + 1) (3 – 2)
= 24
m2 – 2m is divisible by 24. Ans.
5.(D) Let the two digits number be 10x + y.
two digits number in reverse order
= 10y + x
According to question,
� 10 × 2x + 2
y = 10y + x
� 20x – x = 10y – 2

5 = 2 + 4 – 1 = 5 Ans.
7.(B) Let the two digits number be A & B
According to question,
35% of A + B = 120% of B
� 35 A = 20 B
�A 20 4
B 35 7� � � 4 : 7
8.(D) Let the five numbers be x, y, z, u, and v.
According to question,
� x + y + z + 6 = u + v ................(1)
� x + y + z = 2u v ...................(2)
From (1) & (2)
2 u + 6 = u + v
v – u = 6
Neither u nor v can be calculated with the
help of the above relation
��Data inadequate. Cases could be many.
9.(C) Number of different ways in which 4 boys &
2 girls can be seated.
= 6! = 720
When two girls seat together,
No. of arrangements = 5! × 2 = 240
No. of arrangements when girls do not seat
together = 720 – 240 = 480. Ans.
