You can treat 50 * 2525 as (100 * 2525) / 2 and then subtract 65 or
50 * 2525 - 50 - 15 = 50(2525 - 1) - 15 = 50 * 2524 - 15
50 * 2524 is 100 * 2524/2 = 100 * 1262 so 126200 - 15 = 126185
50 * 2525 - 50 - 15 = 50(2525 - 1) - 15 = 50 * 2524 - 15
50 * 2524 is 100 * 2524/2 = 100 * 1262 so 126200 - 15 = 126185

= 126250 - 65 = 126185

2525x50 = 126250
==> 126250 - 65 = 126185
==> 126250 - 65 = 126185
