Direction(10-14): On the basis of the numbers given below, answer the following questions:
266 789 456 763 279
Q10. What is the difference between the two numbers which are exactly divisible by 3 but not by 6?
(a) 26
(b) 226
(c) 333
(d) 612
(e) None of these
S10. Ans.(e)
Sol. First, we have to find the numbers which are divisible by 3 but not by 6. The numbers are are 789 and 279.
So, difference between these numbers is 510.
Q11. If all the digits within the number are arranged in decreasing order,then if the number at unit place is odd, 1 is added to it. Find, which of the following is the sum obtained by adding all the digits at unit’s placeof all the numbers?
(a) 33
(b) 23
(c) 20
(d) 30
(e) None of these
S11. 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’s place is odd, 1 must be added to it i.e.,
662 988 654 764 972
On adding the digits at unit’s place of all the numbers, we get 20 (i.e., 2 + 8 + 4 + 4 + 2).
Q12. If we subtract 1 from even numbers (3-digit even number), then what will be the sum of the digits at unit’s place of all the numbers?
(a) 31
(b) 32
(c) 33
(d) 34
(e) None of these
S12. Ans.(a)
Sol. On subtracting 1 from all even numbers, we get: 265 789 455 63 279.
On adding digit at unit’s place, we get 31 (5 + 9 + 5 + 3 + 9).
Q13. If we add 3 to every even digit which is less than 7 within the number, which one of the following is the second highest number?
(a) 266
(b) 789
(c) 456
(d) 763
(e) 279
S13. 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.
Q14. If all the digits within a number are arranged in such a way that even digits (within a number) are arranged first in increasing order and then the odd digits are arranged. Which one of the following is the third lowest number?
(a) 266
(b) 789
(c) 456
(d) 763
(e) 279
S14. 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.
Q15.A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
HPA, FMZ, DJY, BGX, ?
(a) ZDW
(b) ZEV
(c) YDW
(d) YEV
