In a certain code, the symbol for 0 is * and that for 1 is $. Numbers greater than 1 are to be written only by using the two symbols given above. The value of symbol for 1 doubles everytime it shifts one place to the left (eg. 4 is written as $**; 3 as $$ )
1)460
a)$*$$*$*$$
b)$$$**$$**
c)$*$******
d)$******$
2)17 x 2 / 16 x 4 / 5 x 2 + 6 / 10
a)$**b) $$ c)$$* d)$***
3) value of LCM (12, 14, 18)
a)$*******
b)$*$*****
c)$$$*****
d)$$$$$$**

• the code is binary code.
  * = 0
  $ = 1
  1)460=111001100 so option b) is answer
  2)the given expression yields 4=100 so a) is answer
  3)252 is the lcm .In binary ,11111100 so option d)
