Solutions

Solution (1-5):
S1. Ans. (e)
Sol. First, we have to find the numbers which are divisible by 3 but not by 6. The numbers are 789 and 279.
So, difference between these numbers is 510.

S2. Ans. (c)
Sol. When all the digits within the number are arranged in decreasing order, we get:
662 987 654 763 972
If the digit at unit place is odd, 1 must be added to it i.e.,
662 988 654 764 972
On adding the digits at unit place of all the numbers, we get 20 (i.e., 2 + 8 + 4 + 4 + 2).

S3. Ans. (a)
Sol. On subtracting 1 from all even numbers, we get: 265 789 455 763 279.
On adding digit at unit’s place, we get 31 (5 + 9 + 5 + 3 + 9).

S4. Ans. (b)
Sol. On adding 3 to every even digit which is less than 7, we get:
599 789 759 793 579
Arranging the numbers, 579 < 599 < 759 < 789 < 793
Clearly, we can see that 789 is the second highest number.

S5. Ans. (c)
Sol. When all the numbers are arranged in such a way that even digits are arranged first then the odd digits are arranged in increasing order, we get: 266 879 465 637 279
On arranging the numbers, we get: 266 < 279 < 465 < 637 < 879
Clearly, 456 (465 in the required number) is the third lowest number.

Solution (6-10):
S6. Ans. (b)
Sol. New Arrangement: A D @ 7 M Q % 5 F $ 6 K L & 4 R N # U 5
So, third element from the right end = #

S7. Ans. (c)
Sol. RNU is the correct answer.

S8. Ans. (b)
Sol. New series: A D 7 M Q 5 F 6 K L 4 R N U 5
2nd to the left of 12th from the right = 14th from the right end
So, 14th from the right end = D

S9. Ans. (d)
Sol. New Arrangement: A @ 7 E M Q % 5 $ 6 G K L & 4 R # N 5 V
4th element from the left end = E , 11th element from the right end = 6
