if A leaves remainder of 3 when we divide it by 7 so take A=38 which leaves a remainder of 3 when divided by 7 you can also take other no\'s like 45 etc if B leaves remainder of 5 when we divide it by 7 so take B=26 which leaves a remainder of 5 when divided by 7 you can also take other no\'s like 19 etc so therefore 38-26=12 and when 12/7 gives remainder of 5
