Tanmay had some chocolates with him. He gave one-third of them to Akash and one-fifth of them to Sharad. Tanmay could do so without breaking any chocolate. Which of these could be the number of chocolates Tanmay had in the beginning?

The possible value of X are;

15, 30, 45, 60 etc

Step-by-step explanation:

The parameters given are

Number of chocolates Tanmay had = X

Number of chocolates Tanmay gave to Akash = 1/3 * X

Number of chocolates Tanmay gave to Sharad = 1/5 * X

Whereby 3 and 5 are factors of X, therefore;

3 * 5 = 15 is the lowest single factor of X

The possible values of X starting from the lowest factor are given as follows;

15 * 1 = 15

15 * 2 = 30

15 * 3 = 45

15 * 4 = 60

Hence, the possible value of X are the arithmetic progression a + (n - 1) * d

Where:

a = 15

n = 1, 2, 3, 4, ...

d = 15

Which includes;

15, 30, 45, 60
