n this case, we can take 50, which is a sub multiple of 100 or a multiple of 10 and proceed as follows: 50 -41 = 9, 50 -43 = 7

9 * 7 = 63 (last two digits)

41-7= 43-9 = 34/2 = 17

Since 50 = 100/2, we divide the left hand side number also by 2 while retaining the right hand side. Therefore, the answer will be 2068.
