Analysis of The Pattern

Find the question here! 

Let's try to put it in mathematical equation, 

a + b + C

1. First two digits of answer is product of first two digits a & b i.e. ab.

2. Next two digits of answer are formed by product of first & last digits i.e. a & c = ac.

3. For last two digits of answer, first & last digits are added & then multiplied by second 

 digit like (a+c) × b = cd. Now the places of digits of results are interchanged as dc.

With the same logic applied,

  7 + 2 + 5 = 143542.
