Question

Q.No : 14. A number is divided into two parts, such that one part is 10 more than the other. If the two parts are in the ratio 5 : 3, find the number and the two parts

Answer 1

solution:      

let one part of number = x          

other part of number = x+10  

according to question ,            

x+10/x=5/3          

3(x+10)= 5x          

3x+30 =5x            

30 = 5x -3x            

30 = 2x     or x=30/2        

x=15

one part of number = 15

and other part = 15+10 =25

hence number = 15+25 =40

hope this helps
