7 = 111.
5 = 101.
So simple 5*7 = 35.
Now it will be convert in binary
32 16 8 4 2 1
1 0 0 0 1 1
35=100011.
The same technique will be used if large no occur.

111->7
101->5
7*5=35
35/2=17 --------------> 35%2=1
17/2=8 --------------> 17%2=1
8/2=4 --------------> 8%2=0
4/2=2 --------------> 4%2=0
2/2=1 --------------> 2%2=0
--------------> 1%2=1
Reading in reverse order we get the answer 100011.
101->5

I have a simple idea to solve this kind of problem.
111 --> 7
101 --> 5
7 x 5 = 35
35 --> 100011 is the required answer.
111 --> 7
101 --> 5
7 x 5 = 35
35 --> 100011 is the required answer.

111 --> 7
=> (2^0*1)+(2^1*1)+(2^2*1)
=>(1*1)+(2*1)+(4*1)
=>1+2+4
=>7
Same for 101
try it.
=> (2^0*1)+(2^1*1)+(2^2*1)
=>(1*1)+(2*1)+(4*1)
=>1+2+4
=>7
Same for 101

What is the grammar of this summation @Priyanka?

In binary 1 is written as 001 and 2 is 010, three is 011, 4 is 100, 5 is 101, 6 is 110 and seven is 111 eight is 1000 nine is 1001 and ten is 1010 accordingly 20 is 10100 and 30 is 11110 plus five 101 total would be 10001.
The concept is 1+1=0 and carry forward 1, further if we multiply 7*5=35 it written in binary as 100011 is.
