A number is divided in two parts such that one part is 10 more than the other.if the two parts in the ration5:3 .find the number and the two parts



Suppose that number is X, and its two parts are y and y+10. Then
(y+10)/y = 5/3
i.e. y+10 = 5y/3
or, 3y + 30 = 5y
Therefore, 30 = 2y
Hence, y = 15 and y+10 = 25
That is, the no. is 15+25 = 40 and the two parts are 25 and 15.
