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 will represent the value of $6\frac{2}{4}+5\frac{1}{3}+4\frac{4}{15}$?

Options :

$6\frac{2}{4}+5\frac{1}{3}+4\frac{4}{15} \: = \: \left (6+5+4 \right )+\left ( \frac{2}{5} + \frac{1}{3} + \frac{4}{15} \right )$

$\left (15 \right )+\left ( \frac{6+5+4}{15} \right )= 15+\frac{15}{15}$

$15 + 1 = 16$

(16)_{10} = (10000)_{2} = Δ^{****}

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

Q 2 - Which of the following numbers will be represented by = > > > = = = >

Options :

1 0 0 0 1 1 1 0

= 1 x 2^{7} + 1 x 2^{3} + 1 x 2^{2} + 1 x 2^{1} + 0

= 128 + 8 + 4 + 2 + 0 = 142

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

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 - Which of the following will represent 25?

Options :

∴ (25)_{10} = (11001)_{2} or, ##@@#

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 11?

Options :

So (11)_{10} = (1011)_{2} = +!++
