1.	Replace A, B, C by suitable numerals:\(\begin{equation}\frac{\begin{array}[b]{r}5\,7\,A\\-\,\,C\,B\,8\end{array}}{\,2\,\,\,9\,\,\,3}\end{equation}\)
Answer» Here, in units place, A – 8 = 3 This implies that 1 is borrowed. 11 – 8 = 3 ∴ A = 1 Now in tens place,Then, 7−B=9 1 is borrowed from 7. ∴ 16−B=9 ∴ B = 7 Now in hundreds place, 5−C=2 But 1 has been borrowed from 5. ∴ 4 - C = 2 ∴ C=2 ∴ A=1, B=7 and C=2

Replace A, B, C by suitable numerals:\(\begin{equation}\frac{\begin{array}[b]{r}5\,7\,A\\-\,\,C\,B\,8\end{array}}{\,2\,\,\,9\,\,\,3}\end{equation}\)

Answer»

Here, in units place,

A – 8 = 3

This implies that 1 is borrowed.

11 – 8 = 3

∴ A = 1

Now in tens place,Then, 7−B=9

1 is borrowed from 7.

∴ 16−B=9

∴ B = 7

Now in hundreds place,

5−C=2

But 1 has been borrowed from 5.

∴ 4 - C = 2

∴ C=2

∴ A=1, B=7 and C=2
