Question

two numbers are such that the ratio between them is 3 : 5 if each is increased by 10 , the ratio between the new number so formed is 5 : 7 find the original number

Answer 1

Hey there!

Let the Multiplier be x
Then,

First number = 3x
Second number = 5x

i) Each is increased by 10:

3x + 10/5x + 10 = 5/7

(5x+10) = 7(3x+10)

25x + 50 = 21x + 70

25x - 21x = 70 - 50

4x = 20

x = 20/4

x = 5

So,
First number = 3x = 3(5) = 15
&
Second number = 5x = 5(5) = 25

Hence the original numbers are 15 and 25
