Go through the following information and answer the question carefully.
In a certain code, the symbol for 0 is • and for 1 is #. There is no symbol for rest of the numbers. Numbers greater than 1 are needed to be depicted using the two given symbols. Left shifting of 1 doubles its value each time. Study the following example.
0 is written as •
1 is written as #
2 is written as at
3 is written as ##
4 is written as #•• and so on.
Q 3 - Which of the following will be represented by #••#••#••?
Options :
Answer : A
Explanation
| # | • | • | # | • | • | # | • | • |
| 256 | 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
Now add the numbers below the symbol # only. (Because • represents 0). Hence 256 + 32 + 4 = 292.

Q 6 - The symbol combination **Δ Δ*Δ represents which of the following numbers?
Options :
Answer : D
Explanation
| * | * | Δ | Δ | * | Δ |
| 32 | 16 | 8 | 4 | 2 | 1 |
Now since Δ is the code for 0. Therefore, ignore all the values depicted below Δ. Thus **Δ Δ*Δ = 32 + 16 + 2 = 50
