Question
Replace A, B, C by suitable numerals.
$ \ \ \ \ \ 5\text{ A}\\\underline{+ \ \ 8 \ 7 \ }\\\underline{\text{C} \ \text{ B} \ 3}$
$ \ \ \ \ \ 5\text{ A}\\\underline{+ \ \ 8 \ 7 \ }\\\underline{\text{C} \ \text{ B} \ 3}$

Answer
A + 7 = 13
So, 1 is carried over.
(1 + 5 + 8) = 14. So, B = 4 and 1 is carried over.
And C = 1.
$\therefore$ A = 6, B = 4 and C = 1.
So, 1 is carried over.
(1 + 5 + 8) = 14. So, B = 4 and 1 is carried over.
And C = 1.
$\therefore$ A = 6, B = 4 and C = 1.
