Question

5. Two numbers are in the ratio 1 : 2. If 4 is added to each of them, the ratio becomes
4 : 7. Find the numbers.
​

Answer 1

Step-by-step explanation:

First the ratio was 1:2

so , after adding 4 it becomes 4:7

we can write it as 1x:2x

We can find the the number using the other ratio

1x + 4: 2x + 4 = 4x:7x

[by comparing both]

1x+4 = 4x

3x =4

x = 3/4

Answer 2

Answer:

12 and 24

Step-by-step explanation:

let the numbers be x,y

hence,

1:2

=1/2

=x/y [2x=y]

If,

4 is added to x and y

so the ratios become 4:7=4/7

x+4/y+4=4/7

by cross multiplying

we will get,

7(x+4)=4(y+4)

=7x+28=4y+16

=7x-4y=16-28

=7x-4y= -12------------------------¹

putting value of 2x=y in equation 1

7x-4[2x]= -12

= 7x-8x= -12

= -x= -12

= x=12

as you could see the above bold equation in bracket on the above right side

2x=y

2*12=y

y=24
