Let us assume the unknown number = x
Then
(62.4/100) * x = 17.16
62.4x = 17.6 * 100
62.4x = 1760
x = 1760/62.4
=28.205
= 28.21
Then the unknown number is 28.21. I hope to have made the procedure clear to you and you have got the answer to your question. In future you can follow this procedure to complete such problems with ease.
