35 and 49

Step-by-step explanation:

Let the number be 7x and 5x

7x=7×7=49

Answer 2

Given :-

• Ratio = 5 : 7

• The sum of their numbers is 84

To find :-

• The numbers

Solution :-

Let,

'x' is included in the ratio

Then,

First number = 5x

Second number = 7x

According to the given question,

Sum of these two numbers will be "84"

Now,

⇒5x + 7x = 84

⇒12x = 84

⇒x = 84 / 12

⇒x = 7

Then,

First number = 5x = 5 × 7 = 35

Second number = 7x = 7 × 7 = 49

Therefore, The two number is "35 and 49"

Verification:-

Sum of these two numbers = 84

⇒35 + 49 = 84

⇒84 = 84
