Solutions

Sol 2. Ans.(c)
Sol. 1 + 5 = 6
6 + 7 = 13
13 + 9 = 22
22 + 11 = 33
33 + 13 = 46

Sol 3. Ans.(a)
Sol. 50 weeks = 50 × 7 = 350 days
Anu is 300 days older than Varun.
Sandeep is 350 days older than Anu.
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.

Sol 4. 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, the word MEAT cannot be formed.

Sol 7. 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

Sol 8. Ans.(b)
Sol. 10 – 3 = 12
⇒ 10 – 3 = 7 and 7 + 5 = 12
12 – 4 = 13
⇒ 12 – 4 = 8 and 8 + 5 = 13
14 – 5 = 14
⇒ 14 – 5 = 9 and 9 + 5 = 14
Similarly,
16 – 6 = ?
⇒ 16 – 6 = 10 and 10 + 5 = 15

Sol 9. 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

Sol 10. Ans.(a)
Sol. The sum of all the three numbers in each column is 40.
First column
13 + 11 + 16 = 40
Second column
9 + ? + 20 = 40
⇒ ? = 40 – 29 = 11
Third column
24 + 6 + 10 = 40 Join India's largest learning destination
