Question

Thirty candies were distributed among some children. Relishing the sweet, the whiz-kid among them said, “If we were one short, we would all get one more.” How many kids were there?

Answer 1

Number of candies each kid will get =

According to the question:

Adding to both sides to make L.H.S a perfect square:

As the number of kids cannot be negative, x = 6.

Thus, there was 6 kids.
