28 is divided into two parts in such a way that 65 of one part is equal to 23 of the other. Find the smaller part.
10
Let one part be x.
Then other part = 28 - x
Given that, 65 of one part = 23 of the other.
⇒ 65x = 23(28−x)
⇒ 9x = 5(28 - x)
⇒ x = 10
∴ the other part = 28 - 10 = 18
Hence, the smaller part is 10
