# 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.

At all the options have the same value as denominator and its value is 51 (110011)

60/17 can be written as 180/51, so option c  is the correct answer.
