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 :
Answer : A
Explanation
Δ*Δ*Δ* = 101010
= 1 x 25 + 0 x 24 + 1 x 23 + 0 x 22 + 1 x 21 + 0 x 20
= 32 + 0 + 8 + 0 + 2 + 0 = 42
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 will represent the value of 45 + 36 ÷ 2 - 25 ÷ 5?
Options :
Answer : B
Explanation
45 + 36 ÷ 2 - 25 ÷ 5 - 45 + 18 - 5 = 45 + 13 = 58
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.
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 8 - The symbol arrangement +Δ Δ++ represents which of the following numbers?
Options :
Answer : E
Explanation
Put 1,2,4, 8 and so on below each symbol starting from the right end of the symbol arrangement, We get
| + | Δ | Δ | + | + |
| 16 | 8 | 4 | 2 | 1 |
Now, Since Δ stands for 0, therefore, reject all the values written below Δ s. Thus reject 8 and 4. Now, add the remaining values under each +. Hence the required value of +Δ Δ++ is 16 + 2 + 1 = 19.
