Following quiz provides Multiple Choice Questions (MCQs) related to **Coded Binary Numbers**. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using **Show Answer** button. You can use **Next Quiz** button to check new set of questions in the quiz.

Go through the following information and answer the question carefully.

In a certain code, the symbol for 0 (zero) is * and for 1 is Δ. 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 Δ

2 is depicted as Δ*

3 is depicted as Δ Δ

4 is depicted as Δ** and so on.

Q 1 - Which of the following numbers will be represented by Δ**Δ*Δ?

Options :

Δ**Δ*Δ Δ = (1001011)_{2}

= 1 x 2^{6} + 0 x 2^{5} + 0 x 2^{4} + 1 x 2^{3} + 0 x 2^{2} + 1 x 2^{1} + l x 2^{0} = 64 + 8 + 2 + l = 75

Go through the following information and answer the question carefully.

In a certain code, the symbol for 0 is * and for 1 is Δ. 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 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.

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 :

# | • | • | # | • | • | # | • | • |

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.

Go through the following information and answer carefully.

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 )%

'3' is written as ))

'4' is written as )%% and so on.

Q 4 - Suppose ))% is divided by )). The result will be expressed as

Options :

##@ ⇒ 110 ⇒ 1 x 2^{2} + 1 x 2^{1} + 0 x 2^{0} = 4 + 2 = 6

## ⇒ 11 ⇒ 1 x 2^{1} + 1 x 2^{0} = 2 + 1 = 3

$\frac{\#\#@}{\#\#} \:= \:\frac{6}{3} \:= \:2$ , 2 ⇒ #@

))% = 110 = 1 x 2^{2} + 1 x 2^{1} + 1 x 2^{0} = 4 + 2 = 6

)) = 11 = 1 x 2^{1} + 1 x 2^{0} = 2 + 1 = 3

6 ÷ 3 = 2

Binary equivalent of 2 is )%

Go through following information and answer the question accordingly.

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 depicted as -

'1' is depicted as (

'2' is depicted as (-

'3' is depicted as ((

'4' is depicted as (-- and so on

Q 5 - Which of the following will represent the value of the product 3 x 3 + 1?

Options :

3 x 3 + 1 = 10

(10)_{10} = (1010)_{2} = (-(-

Go through the following question and answer accordingly.

In a certain code, the symbol for 0 (zero) is Δ and for 1 is *. There is no symbol for rest of the numbers. Numbers greater than 1 are needed to be written using the two given symbols. Left shifting of 1 doubles its value each time. Study the following example.

'0' is depicted as Δ

'1' is depicted as *
