Question
Replace A, B, C by suitable numerals:
$ \ \ \ 5 \ \ 7 \ \ \text{A}\\\underline{-\text{C} \ \text{B} \ \ 8}\\\underline{ \ \ \ 2 \ \ 9 \ \ \ 3 \ \ }$

Answer

A - 8 = 3
This implies that 1 is borrowed.
11 - 8 = 3
⇒ A = 1
Then, 7 - B = 9
1 is borrowed from 7.
$\therefore$ 16 - B = 9
⇒ B = 7
Further, 5 - C = 2
But 1 has been borrowed from 5.
$\therefore$ 4 - C = 2
⇒ C = 2
$\therefore$ A = 1, B = 7 and C = 2
