Question

the difference of two numbers is9and they are in the ratio 4ratio 7.find the numbers​

Answer 1

Answer:

Ratio of the number= 4:7

Difference of number= 9

Let us take one number= 4x

another number= 7x

7x-4x=9

3x=9

x=9/3

x=3

Therefore the 1st number= 4x=4 (3)=12

2nd number =7x=7 (3)=21

Proof : 21-12?

Answer 2

Since the nos. are in ratio 4:7,therefore let the nos. be 4x and 7x.

Now, According to given condition:

7x-4x=9

This gives, 3x=9 and hence x=3.

Therefore now the two nos. are 4*3 and 7*3,i.e.,12 and 21.

So the two numbers are 12 and 21.
