CAT Brain Teaser

Well, this can be considered off-topic. A brain teaser in CAT. Only 2% students were able to solve this in the CAT Exam. They should have been really sick :) Enough build up, lets see what the problem is.

Given,

5+3+2 = 151022
9+2+4 = 183652
8+6+3 = 482466
5+4+5 = 202541

Then, 7+2+5 = ???


Solution:

5+3+2 = (5*3)(5*2)(5*3 + 5*2 - 3)
9+2+4 = (9*2)(9*4)(9*2 + 9*4 - 2)
8+6+3 = (8*6)(8*3)(8*6 + 8*3 - 6)
5+4+5 = (5*4)(5*5)(5*4 + 5*5 - 4)

Hence,

7+2+5 = (7*2)(7*5)(7*2 + 7*5 - 2) = 143547

Cheers!!
