Go through the following information and answer the question carefully.

In a certain code, the symbol for 0 (zero) 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 depicted as @

'1' is depicted as $

'2' is depicted as $@

'3' is depicted as $$

'4' is depicted as $@@ and so on.

'0' is depicted as *

'1'is depicted as Δ

'2' is depicted as Δ*

'3' is depicted as ΔΔ

'4' is depicted as Δ** and so on

Q 2 - Which of the following codes will give odd number as the result after being decoded?

Options :

Since I is depicted as Δ, the code which will end with Δ will give odd number as a result, Obviously, it is option A.

Go through the following information and answer the question carefully.

Symbols 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 }<

'3' is written as }}

'4' is written as }<< and so on.

Q 3 - Which of the following will represent the value of }}<}?

Options :

} | } | < | } |

8 | 4 | 2 | 1 |

Since < is he code for 0, ignore the value written below <. Thus }}<} = 8 + 4 + 0 + 1 = 13
