Question

Q7. Two numbers are in the ratio 5:3. If they differ by 18, what are the numbers?

Answer 1

Answer:

Let the ratio be 5x:3x.

According to Question,

5x - 3x = 18

=> 2x = 18

=> x = 9

Hence, first number = 5 × 9 = 45

Second number = 3 × 9 = 27

Answer 2

Answer:

First number is 45 and Second number is 27

Step-by-step explanation:

Let the rational between numbers be x. As the numbers are in 5 : 3 ratio

Hence the numbers can be written as 5x and 3x

As per the statement the difference in these numbers is 18. Thus

5x-3x=18…Eq.1

Solving this equation

5x-3x=18

2x=18

x=18/2

x=9

Therefore rational x between the number is 9; Now calculate the numbers by putting the value of rational x.

5x means

5×9

=45

First number is 45

3x means

3×9

=27

Second number is 27
