Question

Please give me Answer

Answer 1

Hey!!!
________________________________
The answer is 143547.

The pattern of numbers on the LHS (from the 4 examples) enable us to arrive at the answer.

Let's explain it using the first example given in the question which is 
5+3+2= 151022

Let 5=a
      3=b
      2=c
Now, the pattern for the answer on the RHS is:
First two digits= a×b
Next two digits= a×c
Last two digits= [(a×b)+(a×c)]-b

Accordingly, applying the same to 7+2+5 we will get:
First two digits= 7×2=14
Next two digits= 7×5=35
Last two digits= 14+35-2=47

Thus, 7+2+5= 143547
