**Solutions**

S1. Ans.(c)

Sol.

S2. Ans.(c)

Sol.

S3. Ans.(a)

Sol. 50 Weeks = 50×7 = 350 days

Ann is 300 days older than Varun.

Sandeep is 350 days older than Ann.

Sandeep is (350+300) days older than Varun.

Sandeep was born on Tuesday.

650 days = 650/7

= 92 weeks 6 days

Number of odd days = 6

So, Varun was born 6 days after Tuesday, i.e., Monday.

S4. Ans.(b)

Sol. The present age of Hema = 40-10 = 30 years

The age of Hema 10 years ago = 30-10 = 20 years

The age of Geeta 10 years ago = 20/2=10 years

So, the present age of Geeta = 10+10 = 20 years.

S5. Ans.(b)

Sol. There is only one ‘B’ in the given word. So, the words BAILABLE and BIBLE cannot be formed.

There is no ‘T’ letter in the given word. So, he word MEAT cannot be formed.

S6. Ans.(a)

Sol.

S7. Ans.(d)

Sol.

S8. Ans.(b)

Sol. 2×16 = 8

⇒ 16/2=8

8×8 = 1

⇒ 8/8=1

6×12 = 2

⇒ 12/6=2

Therefore,

12×144 =?

⇒ ? = 144/12=12

S9. Ans.(c)

Sol. First arrangement

2×2×2×2 = 16

Second arrangement

3×3×3×3 = 81

Third arrangement

? = 5×5×5×5 = 625

S10. Ans.(b)

Sol. First column

(1+2+4+3) ×5 = 10×5 = 50

Second column

(3+4+5+2) × 5 = 14×5 = 70

Third column

? = (7+4+9+3) × 5

⇒ ? = 23×5 = 115
