(a) 27

(b) 108

(c) 68

(d) 72

Ans. A

**Explanation:**

**Numbers are alternatively multiplied by 3 and divided by 2.**

**So, the next number = 54 ÷ 2 = 27.**

**2. 2, 6, 12, 20, 30, 42, 56, (….)**

(a) 61

(b) 64

(c) 72

Ans. C

**Explanation:**

**The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.**

**So, the next number is 8 x 9 = 72.**

**3. 4, -8, 16, -32, 64, (….)**

(a) 128

(b) -128

(c) 192

**4. If 7 + 5 = 21 and 10 + 5 = 51, what is 8 + 9 = ?**

(a) 17

(b) 16

(c) 71

(d) 69

Ans. (c)

**7 + 5 = 12 By reversing the digits we get 21**

**5. The age of Mohan’s father today is Five times as that of his age. After 8 years the age of his father will be three times that of his age. What is the present age of Mohan?**

(a) 16

(b) 24

(c) 20

(d) 8

Ans. (d)

**3 (x + 8) = 5x + 8**

** 3x + 24 = 5x + 8**

** 5x – 3x = 16**

** 2x = 16**

** x= 8**

**6. If 533 + 780 = 21, 931 + 453 = 20**

**Then what is the value of 789 + 987 = ?**

(a) 42

(b) 48

(c) 43

(d) 44

Ans. (c)

**533 + 780 = 26-5 = 21 (5+3++3+7+8+0=26) **

**Similarly**

**789 + 987 = 48 – 5 = 43 (7 + 8 + 9 + 9 + 8 + 7 = 48)**
