1.	Replace A, B, C by suitable numerals.\(\begin{equation}\frac{\begin{array}[b]{r}C\,\,B\,\,5\\- \,\ 2\,\,\,\,8\,\,\,A\end{array}}{2\,\,\,5\,\,\,\,9}\end{equation}\)
Answer» Now in units place, 5 - A = 9 This states that borrowing is involved. Ie. 10 + 5 - A = 9 ∴ A = 6 Now in tens place, as 1 is borrowed from hundreds place and also lent, B – 5 +10 - 1 = 8 B = 4 Now in hundred place, as 1 is lent, C – 2 – 1 = 2 C = 5

Answer»

Now in units place,

5 - A = 9

This states that borrowing is involved.

Ie. 10 + 5 - A = 9

∴ A = 6

Now in tens place, as 1 is borrowed from hundreds place and also lent,

B – 5 +10 - 1 = 8

B = 4

Now in hundred place, as 1 is lent,

C – 2 – 1 = 2

C = 5
