Questions and Answers

In the given question if + means -, × means /, - means + and / means × then find out the answer of the following question.

Q 1 - (108 × 9) × 4/5

Options :

A - 25

B - 45

C - 15

D - 17

Answer : C

Explanation

108/9 = 12. 12/4 = 3. 3 × 5 = 15.

If 0 is to be replaced by 1, 1 is replaced by 2. 7 is replaced by 8 and 8 is replaced by 9 and 9 is replaced by 0. Then answer the following question.

Q 2 - 78 - 12 - 13 - 14

Options :

A - 17

B - 14

C - 161

D - 31

Answer : A

Explanation

89 - 23 - 24 - 25 = 17

If 0 is written as *

1 is written as .

2 is written as .*

3 is written as ..

4 is written as .** answer the following

Q 3 - If is added to .**, what will be the sum?

Options :

A - **..

B - .*..

C - *..*

D - .*.*.

Answer : B

Explanation

as = 4 + 2 + 1 = 7 and .** = 4 + 0 + 0 = 4. So 7 + 4 = 11 and .*.. = 8 + 0 + 2 + 1 = 11. Hence option B is correct.

If + means -, × means /, - means + and / means × then find out the answer of the following question.
