Ans : a

• They are all of the form

  “4AB”, “34B”, and “3B4”, where neither A nor B is 4

  Case 1:  The number of 3-digit numbers of type “4AB”

  We can choose A as any of the 9 digits {0,1,2,3,5,6,7,8,9}
  We can choose B as any of the 9 digits {0,1,2,3,5,6,7,8,9}

  So there are 9×9 = 81 ways for Case 1.

  —————————————————-

  Case 2: The number of 3-digit numbers of type “34B”

  We can choose B as any of the 9 digits {0,1,2,3,5,6,7,8,9}

  So there are 9 ways for Case 2.

  ———————————–

  Case 3: The number of 3-digit numbers of type “3B4”

  Same as Case 2: We can choose B as any of the 9 digits {0,1,2,3,5,6,7,8,9}

  So there are 9 ways for Case 2.

  —————————————–

(a) 80
(b) 81
(c) 83

24. There are four persons A,B,C,D and A has some coins. A gave half of the coins to B and 4 more beside B gave       half of the coins to C and 4 more beside C gave half of the coins to D and 4 more beside . Both B and D end up with same number of coins how many coins did A have originally ?
(a) 96
(b) 84
(c) 72
(d) 64

Ans : c

Let A has x number of coins, then as per question:

Both B and D end up with same number of coins i.e.

Remaining No. of coins of B = No. of coins of D

=

⇒ x = 72

25. While adding the first few continuous natural numbers. a candidate missed one of the numbers and wrote the answer as 177. what was the number missed ?
(a) 11
(b) 12
(c) 13
(d) 14

Ans : c

• Sum of n natural numbers = (n*(n+1))/2.
• if n = 19, then the sum = 190.
• Therefore  number missed = 190-177 = 13.

26. Four metal rods of lengths 78 cm, 104 cm, 117 cm and 169 cm are to be cut  in to parts of equal length, Each part must be as long as possible what is the maximum number of pieces that con be cut ?
(a) 27
(b) 36
(c) 43
(d) 480

Ans : b

• HCF of 78, 104, 117 and 169 is 13.
• Hence we get 6, 8, 9 and 13 pieces.=> Total 36 pieces

27. In an examination, there are three subjects A, B and C. Student has to pass in Each subject. 20% student failed in A, 22% students failed in B and 16% failed in C. The total number of students passing the whole examination lies between?
(a) 42% and 84%
(b) 42% and 78%
(c) 58% and 78%
(d) 58% and 84%

Ans : a

• There are three subjects A, B, and C in an examination.Total percentage of students failed individually in each subject = n (A ∪ B ∪ C)

  = 20 + 22 + 16 = 58

• Total percentage of students failed commonly in subjects = n (A ∩ B ∩ C) = 16
• Hence total %age of student passing the whole examination lies between 100 – 58 & 100 – 16 ⇒ 42% and 84%

28.  There is a family of 6 persons A, B, C, D, E and F. There are two married couples in the family. The family members are lawyer, teacher, salesman, engineer, accountant and doctor.

(d) 20

Ans : c

• Right angle (90 degrees) occurs twice every hour => From 1 to 10 pm it will occur 18 times.

30. There are 240 balls and n number of boxes B₁, B₂, B₃, … , B_n. The balls are to be placed in the boxes such that should contain 4 balls more than B₂, B₂ should contain: 4 balls more than B₃, and so on. Which one of the following cannot be the possible value of n ?
(a) 4
(b) 5
(c) 6
(d) 7

Ans : d

Number of boxes B₁, B₂, B₃, … B_n = n

Let B₁ box contains x balls, then as per question:

B₁    B₂     B₃ … B_n

↓      ↓       ↓

x   x – 4    x – 8 … x – (n – 1) 4

Sum = x + (x – 4) + (x – 8) + …+ {x – (n – 1) 4} = 240

⇒ nx – 4 [1+ 2 + 3 + … + (n –1)} = 240

⇒ x =   

= 

⇒ x =  

Since x is fractional for n = 7. So, n = 7 cannot be possible.

2nd Method:

• If we take 4 boxes the minimum number in 54 then 58 then 62 and finally 66 if 5 boxes, then minimum is 50, 54, 58, 62 and 66. If there are 6 boxes, then minimum balls are 30, 34, 38, 42, 46, 50.
