Answer :

(125 × 75) can be written as (100+25)(100-25)

using identity -


(100+25)(100-25) = -


= 10000 - 625


= 9375


now (126 × 74) can be written as (100+26)(100-26)


using identity -


(100+26)(100-26) = -


= 10000 - 676


= 9324


now putting values in question


(125 × 75) – (126 × 74) = 9375-9324


= 51
