Question

Two number are in the ratio 5:7 and there sum are 720 find the number

Answer 1

Answer:

the numbers will be 300 and 420.

Step-by-step explanation:

Let the ratio be x

therefore the ratio will become 5x:7x...

now given, sum of the numbers is 720.

so let, one number be 5x and another be 7x.

∴ 5x + 7x = 720

=) 12x = 720

=) x = 720/12

=) x = 60.

therefore, the first no. will be; 5x =) 5 × 60 =) 300.

and the second number will be; 7x =) 7 × 60 =) 420.
