Question: 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) $$$*$
D) $**$$
how to solve these type of problems?

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
