If 532=151012, 924=183662, 863=482460, 545= 202504 then 725=?

Lets just look at 532, 924, 863 and 545 and notice we are working towards 725.

725 ends in 5 and thus we must say 2 x  532 - 924 = 140, to make it end in a zero.

Similarly, 532 + 863 = 1395 which ends in a 5, so we are working towards the final answer.

However, note we already have a number ending in 5 (545), so we will say

1395 - 2 x 545 = 305 (which again ends in a five, and we are now approaching the answer.)

Now, if we say 140*3 + 305 it equals 725, which is the number we are looking for. Now, we need to repeat the process for the number that are equivalent to the above.

Hence,

2 x (151012) - (183662) = 118362

(151012) + (482460) = 633472

(633472) - 2 x (202504) = 228464

Finally,

(118362) * 3 + 228464 = 583550. (Final answer.)
