Q 2 - 71 + 72 + 73 - 84

Options :

A - 154

B - 156

C - 178

D - 189

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.
