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 :
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 :
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 :
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.
