Question

A number is divided into two parts such that one parts is 10 more than the other if the two parts are in the ratio of 5.3 find the number and the two parts

Answer 1

ratio of 2 parts=5:3
let common multiple is x
so, 1st part=5x
2nd part=3x
but given condition
5x=3x+10
5x-3x=10
2x=10
x=5
so, parts are 5x=5×5=25
3x=3×5=15
& no. is 15+25=40
