Question

EXERCISE
31.
Divide 49 into 2 parts, such that if larger part is increased by 6 and smaller
part is decreased by 11, then ratio becomes 9 : 2.​

Answer 1

Answer:

A number is divided in to 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.

solution:

let one part of number = x

therefore, 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

therefore one part of number is 15.

and the other part is 15+10=25

HENCE THE NUMBER IS 25.
