Question

one half of a number is equal to one third of its succeeding number. find the first number

Answer 1

Let the number be x
Hence the succeeding number is (x + 1)
0ne half of the first number is (x/2)
One third of the succeeding number is (x + 1)/3
Given (x / 2) = (x+1) / 3
⇒ 3x = 2(x + 1)
⇒ 3x = 2x + 2
⇒ 3x − 2x = 2
∴ x = 2
Hence the first number is 2.
