1. Q1.Select the set in which the numbers are related in the same way as are the numbers of the following set. (NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/ subtracting/ multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed) (5, 4, 2) (9, 9, 3)

   • A.(21,39,1)
   • B.(5,2,6)
   • C.(24,43,34)
   • D.(17,6,5)
   Show answer

   Answer: A. (21,39,1)

   Given sets: (5, 4, 2) (9, 9, 3) The pattern followed here is: (1st term × 2) – (3rd term × 3) = 2nd term. So, for (5, 4, 2) (5 × 2) – (2 × 3) ⇒ 10 – 6 = 4 And, for (9, 9, 3) (9 × 2) – (3 × 3) ⇒ 18 – 9 = 9 Similarly, upon checking option (1), we gt (21 × 2) – (1 × 3) ⇒ 42 – 3 = 39 Hence, it is the correct option.

2. Q2.Seven people, A, B, C, D, E, F and G, are sitting in a straight row, facing north. Only 2 people sit to the right of D. G is an immediate neighbour of D. Only 3 people sit between A and G. Only 2 people sit between B and C. E is not an immediate neighbour of C. F sits to the immediate right of G. Who sits to the immediate left of A?

   • A.E
   • B.C
   • C.D
   • D.B
   Show answer

   Answer: B. C

   Given that: Seven people are sitting in a straight row facing north. As per the statements in the question, following sitting arrangement can be Facing made: C A E B D G F North Hence, C sits to the immediate left of A.

3. Q3.If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, what will come in place of ‘?’ in the following equation? 79 ÷ 64 × 8 −7 + 12 = ?

   • A.123
   • B.117
   • C.138
   • D.147
   Show answer

   Answer: A. 123

   Given equation: 79 ÷ 64 × 8 – 7 + 12 = ? After interchanging the signs as per question, we get 79 + 64 ÷ 8 × 7 – 12 = ? According to BODMAS rule ⇒ 79 + 8 × 7 – 12 ⇒ 79 + 56 – 12 ⇒ 135 – 12 = 123 Hence, 123 is the correct answer.

4. Q4.Two statements are given followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: All keys are locks. No door is a lock. Conclusions: I. Some locks are doors. II. Some locks are keys. III. No key is a door.

   • A.Both conclusions I and II follow.
   • B.Conclusions I, II and III follow.
   • C.Both conclusions II and III follow.
   • D.Both conclusions I and III follow.
   Show answer

   Answer: C. Both conclusions II and III follow.

   . Given equation: 42  7 + 11 × 87 – 12 = 141 Upon checking option 3 and interchanging × and +, we get 42  7 × 11 + 87 – 12 = 141  6 × 11 + 87 – 12 = 141  66 + 87 – 12 = 141  153 – 12 = 141  141 = 141 LHS = RHS Hence, it is the correct option.

5. Q5.Which two signs should be interchanged to make the given equation correct? 42 ÷ 7 + 11 × 87 – 12 = 141

   • A.÷ and –
   • B.÷ and +
   • C.× and +
   • D.– and ×
   Show answer

   Answer: C. × and +

   Given equation: 42 ÷ 7 + 11 × 87 – 12 = 141 Upon checking option 3 and interchanging × and +, we get 42 ÷ 7 × 11 + 87 – 12 = 141 ⇒ 6 × 11 + 87 – 12 = 141 ⇒ 66 + 87 – 12 = 141 ⇒ 153 – 12 = 141 ⇒ 141 = 141 LHS = RHS Hence, it is the correct option.

6. Q6.Which of the following numbers will replace the question mark (?) in the given series? 270, 241, 212, ?, 154, 125

   • A.198
   • B.186
   • C.183
   • D.192
   Show answer

   Answer: C. 183

   . Given series: 270, 241, 212, ?, 154, 125 The pattern followed here is: 270 – 29 = 241 241 – 29 = 212 212 – 29 = 183 183 – 29 = 154 154 – 29 = 125 Hence, 183 is the missing number.

7. Q7.Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term. 25 : 18 :: 37 : ? :: 49 : 36

   • A.29
   • B.32
   • C.30
   • D.27
   Show answer

   Answer: D. 27

   Given pairs: 25 : 18 :: 37 : ? :: 49 : 36 The pattern followed here is: 1st term – sum of numbers in 1st term = 2nd term So, for (25 : 18) 25 – (2 + 5) ⇒ 25 – 7 = 18 And, for (49 : 36) 49 – (4 + 9) ⇒ 49 – 13 = 36 Similarly, for (37 : ?) 37 – (3 + 7) ⇒ 37 – 10 = 27 Hence, 27 is the correct answer.

Shambhavi is an immediate neighbour of both Jigyasa and Avni. Tarun is sitting third to the left of Jigyasa. Meera is sitting second to the right of Avni. Who is sitting second to the left of Jigyasa?

   • A.Meera
   • B.Naina
   • C.Avni
   • D.Tarun
   Show answer

   Answer: A. Meera

   Given that: Meera Tarun Six students are sitting around a circular table facing the centre. Naina Avni As per the questions, following sitting arrangement can be made: Hence, Meera is sitting second Jigyasa Shambhavi to the left of Jigyasa.

   • A.HINO
   • B.GNMI
   • C.HNIM
   • D.GINO
   Show answer

   Answer: C. HNIM

   Given series: BRCQ, EPFO, ?, KLLK, NJOI The pattern followed here is: B R C Q – 3 – 4 – 3 – 4 E P F O – 3 – 4 – 3 – 4 H N I M + 3 – 2 + 3 – 2 K L L K + 3 – 2 + 3 – 2 N J O I Hence, HNIM is the correct answer.

10. Q10.A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example, ‘Q’ can be represented by 12, 43, etc. and ‘M’ can be reprresented by 67, 99, etc. Similarly, you have to identify the set for the word ‘PRICE‘.
