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) $$$*$
D) $**$$

Convert the number into its equivalent binary form,then repace 1&0 with* &$

For a nine digit number, the values $ will take at each position will be

256 128 64 32 16 8 4 2 1

This is because, the value doubles itself with every left shift. Now in the problem, if there is a '$', take it's corresponding value from the above code and find the sum of all such '$' values. For eg, to represent 260,

$*****$**

The first $ from left has value 256 and the second $ has value 4. 256+4=260.

answer is not getting correctly by just convert the value into binary format. plz explain me how 17 can be represent as $$**$$
