QUESTION: 1

Solution:
Let the ages of father and son 10 years ago be 3x and x years respectively.

Then, (3x + 10) + 10 = 2[(x + 10) + 10]

⇒ 3x + 20 = 2x + 40

⇒ x = 20

∴ Required ratio = (3x + 10) : (x + 10) = 70 : 30 = 7 : 3

Then, (3x + 10) + 10 = 2[(x + 10) + 10]

⇒ 3x + 20 = 2x + 40

⇒ x = 20

∴ Required ratio = (3x + 10) : (x + 10) = 70 : 30 = 7 : 3

QUESTION: 5

Which fraction comes next in the sequence 1/ 2 , 3 /4 , 5/ 8 , 7/ 16 , ?

Solution:

Clearly, the numerators of the fractions in the given sequence form

the series 1,3,5,7 in which each term is obtained by adding 2 to the previous terms

The denominators of the fractions form the series

2, 4, 8, 16 i.e. 2^{1}, 2^{2}, 2^{3}, 2^{4}

So, the numerator of the next fraction will be (7 + 2) i.e. 9

and the denominator will be 2^{5}

Thus, the next term is 9 32

QUESTION: 6

∴ Required probability

= 52 100 = 0.52

**In each of these questions two equations numbered I & II are given. You have to solve both the equations and give answer**

I. a^{2} + 5a + 6 = 0

II. b^{2} + 3b + 2 = 0

Solution:

I. a^{2} + 5a + 6 = 0

⇒ a^{2} + 2a + 3a + 6 = 0

⇒ a (a + 2) + 3 (a + 2) = 0

⇒ (a + 2) (a + 3) = 0

⇒ a = -2 or -3

II. b^{2} + 3b + 2 = 0

⇒ b^{2} + 2b + b + 2 = 0

⇒ b (b + 2) + 1 (b + 2) = 0

⇒ (b + 1) (b + 2) = 0

⇒ b = -1 or -2

a ≤ b

QUESTION: 14

**In each of these questions two equations numbered I & II are given. You have to solve both the equations and give answer**

I. 2a^{2} + 3a + 1 = 0

II. 12b^{2} + 7b + 1 = 0

Solution:

I. 2a^{2} + 3a + 1 = 0

⇒ 2a^{2} + 2a + a + 1 = 0

⇒ 2a (a + 1) + 1 (a + 1) = 0

⇒ (a + 1) (2a + 1) = 0

⇒ a = -1 or - 1212

II. 12b^{2} + 7b + 1 = 0

⇒ 12b^{2} + 3b + 4b + 1 = 0

⇒ 3b (4b + 1) + 1 (4b + 1) = 0

⇒ (3b + 1) (4b + 1) = 0

⇒ b = - 1/3 or - 1/4

a < b
