**Solutions**

**S1. Ans.(b)**

**Sol. The correct pattern is +6, +8, +10, +12, +14.**

**So, 45 is wrong and must be replaced by (30 + 10) i.e. 40.**

**S2. Ans.(b)**

**Sol. 3 is subtracted from each number and the result divided by 2 to obtain the next number of the series.**

**So, 46 is wrong and must be replaced by ((109-3)/2) i.e. 53.**

**S3. Ans.(a)**

**Sol.**

**S4. Ans.(a)**

**Sol. The series is abc/bca/cab/abc/bca. Thus, the letters change places in a cyclic order.**

**S5. Ans.(a)**

**Sol. In the first row, 3 × 1 = 3, 6 × 1 = 6, 3 + 6 = 9**

**In the second row, 8 × 4 = 32, 3 × 2 = 6, 32 + 6 = 38**

**In the third row, 3 × 5 = 15, 4 × 3 = 12**

**So, missing number = 15 + 12 = 27.**

**S6. Ans.(d)**

**Sol. Interchanging (+ & ÷) and (2 & 4), we get:**

**(a) 4 ÷ 2 + 3 = 3 or 5 = 3, false**

**(b) 2 ÷ 4 + 6 = 1.5 or 6.5 = 1.5, false**

**(c) 2 + 4 ÷ 3 = 4 or 10/3=4, false**

**(d) 4 ÷ 2 + 6 = 8 or 8 = 8, true**

**Hence, the answer is (d).**

**S7. Ans.(b)**

**Sol. Since Pooja and Yashita exchange places, so Pooja’s new position is the same as Yashita’s earlier position. This position is 17th from the right and 10th from the left.**

**∴ Number of girls in the row = (16 + 1 + 9) = 26.**

**S8. Ans.(b)**

**Sol.**

**S9. Ans.(c)**

**Sol. The first, sixth, seventh and ninth letters of the word PROMENADE are P, N, A and E respectively. The words formed are NAPE, NEAP and PANE.**

**S10. Ans.(a)**

**Sol. The new series becomes:**

**A B C ⋆ E F G ⋆ I J K ⋆ M N O ⋆ Q R S ⋆ U V W ⋆ Y Z**

**Required letter = 14 – 7 = 7**

**So, 7th letter from the left = G**
