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

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.
