34. What number should be added to 231228 to make it exactly divisible by 33?

[CDS 2012]

(a) 1 (b) 2 (c) 3 (d) 4

answer

1. (C) 4 is at the place of ten thousand. /. Required place value

= 4 x 10000 =40000

2. (a) 7 is at the thousand place. /. Required place value

= 7 X 1000 = 7000

3. (c) 6 is at the place of crore. .’. Required place value

= 6 x 10000000 =6 x 107

4. (a) Face value is the value of digit itself. .”. Required face value of 7 = 7

5. (d) Face value is the value of digit itself. /. Required face value = 6

6. (a) The face value is the value of digit itself. So, required sum = 9 + 6 = 15

7. (d) The face value is the value of digit itself. So, required difference = 7-2 = 5

8. (6) Place value of 8 = 800

and face value of 8 = 8 ∴ Required sum = 800 + 8 = 808

9. (a) Place value of 4 = 4000

and face value of 4 = 4 ∴ Required difference = 4000 – 4 = 3996

10. (c) Place value of 6 = 600

and face value of 9 = 9 ∴ Required sum = 600 + 9 = 609

11. (a) Place value of 4 = 4000

and face value of 3 = 3 .’. Required difference = 4000 – 3 = 3997

Hence, when 121012 is divided by 12, then remainder is 4.

13. (d) The sum of place values of 2 in

2424 = 2 X 1000 + 2X10 = 2000 + 20 = 2020

14. (c) 92 and 85 are coprime numbers because their HCF is 1.

15. (a) 1st prime number = 2 and 2nd prime number = 3

.’. Required sum = 2+3 = 5

16. (c) 1st natural number = 1 and 1 st prime number = 2

Required product = 1×2 = 2

17. (6) 1st natural number = 1,

1 st whole number = 0 and 1 st prime number = 2 ∴ Required product = 1x0x2 = 0

18. (a) 1st whole number = 0

Clearly, when any number is multiplied with 0 (the 1st whole number), then the result is 0.

19. (d) A proven fact.

21. (6) 53 has only two factors itself and 1. Hence, it is a prime number.

22. (d) Prime numbers less than 40 are

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37

23. (d) Dividend = 445 and divisor = 5

25. (a) Given, Divisor (d) = 13, Quotient (Q) = 30

Remainder {R) = 12 and Dividend (D) = ?

We know that,

D=dxQ+R D = 13X30 + 12 = 390 + 12 = 402

26. (c) It is clear from the expression that remainder is 18.

27. (a) Given,

Quotient (Q) = 41, Divisor (d) = 19 Remainder (.R) = 4 and Dividend (D) = ? ∴ Dividend D = dxQ + £ = 19×41 + 4 =

779 + 4 = 783

28. (6) Let the number be x. According to the question

∴ Number to be added = (23 – 22) = 1

30.(C) Divisor = 5 X Remainder = 5 X 46 = 230 Also, 10 x Quotient = 230

Quotient = 23 We know that

Dividend = (Divisor X Quotient) + Remainder ∴ Dividend = (230 x 23) + 46

= 5290 + 46 = 5336

(d) Let two consecutive odd number be (x + 1) and (x + 3). According to the question,

(x + 1) (x + 3) = 6723 => x

2

+ 3x + x + 3 = 6723

=> x

z

+ 4x+3 = 6723

=> x2

+4x+3-6723 = 0 => x

z

+ 4x – 6720 = 0

=> x

2

+ 84x – 80x – 6720 = 0

32. (c)

33. (6) Let be the ten’s digit be x and unit’s digit be y. The two-digit number = lOx + y (where, x > y)

According to the question,

x + y = 14 …(i)

and x – y = 2 … (ii)

Solving Eqs. (i) and (ii), we get

x = 8 and y = 6 .’. Required product = 8 x 6 = 48

34. (c) Given, 33)231228(7006

231 228 198 30 Now, 33 – 30 = 3

.’. On adding 3 to 231228, it is completely divisible by 33.
