Questions and Answers

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 :

A - ****Δ

B - Δ***Δ

C - Δ**Δ*

D - Δ**Δ

E - None of these

Answer : E

Explanation

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

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

$15 + 1 = 16$

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 :

A - 292

B - 324

C - 264

D - 296

E - None of these

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.

Go through the following information and answer the question carefully.

(68)10 = (1000100)2 Δ*** Δ**

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 numbers will be represented by +!!!+?

Options :

A - 22

B - 31

C - 14

D - 17

E - None of these

Answer : D

Explanation

Put 1,2,4,8 and so on below each symbol starting from the right end of symbol arrangement, we get.

+ ! ! ! +
16 8 4 2 1

Now since ! stands for 0, therefore , reject all the values depicted below the !. Thus, reject 8,4 and 2. Now, add the remaining values under each !. Hence the required value of +!!!+ is 16 + 1 = 17.

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 *

'2' is depicted as *Δ

'3' is depicted as **

'4' is depicted as *Δ Δand so on.

Q 6 - The symbol combination **Δ Δ*Δ represents which of the following numbers?

Options :

A - 28

E - None of these

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
