In a certain code, the symbol for 0 is # and for 1 is =. There is no symbol for rest of the numbers. Numbers greater than 1 are needed to be written using the two given symbols. Left shifting of 1 doubles its value each time. Study the following example.

0 is written as #

1 is written as =

2 is written as =#

3 is written as ==

4 is written as =## and so on

Q 1 − Which of the following will represent 2x2+3x2+3x3+2×2?

**Options :**

**Answer - B**

**Explanation**

Here the solution is 23. After dividing this number with 2, we will get remainder as 101111. This means the symbol will be =#===.
