Binary Numbers (5 Questions)
In a certain code, the symbol for 0 (zero) is. * and that for 1 is $. The numb.:rs greater than 1 are to be written only by using the two symbols given above. The value of the symbol for 1 doubles itself every time it shifts one place to the left.
(For example, 4 is written as $**; and; 3 is written as $$)

(6) 260 can be represented as:
A) $****$**
B) $$*$$$$$
C) $$*$$$$**
D) $*****$**

(7) 60 / 17 can also be represented as:
A) $$$*$*** / $$**$$
B) $$$***** / $$**$$
C) $*$$*$** / $$**$$
D) $$*$*$** / $$**$$

(8) $***$ can be represented as:
A) $$$ / $*
B) $*$**- $$
C) $*$*$- $$
D) $$$***$ - $$

(9) 30^2 can be represented as:
A) ($$*$$ ) $*+ $*$*$$*$
B) ($$*$$ ) $* + $$****$
C) ( $$*$$ ) $$ + $*$****
D) ( $$*$$ ) $$ + $*$**$

(10) 11x 17 / 10 + 2 x 5 + 3 / 10 can also be represented as:
A) $*$$*
B) $*$$$
C) $$$*$
D) $**$$

6) 260
binary equivalent=10000100
so jus replace 1 with $  and 0 with *

7)60/17 is also equivalent to 180/51
coz $$**$$==110011===== binary equivalent of 51 which is 17*3
hence 60*3=180
therefore 60/17 is also = 180/17
===10110100/110011
===$*$$*$**/$$**$$
hence option C is correct

8)$***$
===10001 which is ===17
option B is $*$*$-$$
               ===10101-11
                ===20-3====17
hence option B is correct

RE: Binary Numbers (5 Questions)In a certain cod...
Mostly convert the binaries into decimals thats formats you are familiar with. It will take time... So attempt last.

The given number is divided by 2 then the remainder is denoted by 1 & 0 then we simply wrote the symbols for that numbers
