Two numbers are in the ratio 5:2. If the sum of the numbers is 70, find the numbers.​

Answer 1

Answer:

50 and 20

Step-by-step explanation:

Let the ratio be 5x:2x.

According to Question,

5x+2x = 70

=> 7x = 70

=> x = 10

Hence, the numbers are 50 and 20.

Answer 2

Answer:

Let one number be x. Therefore, according to the question, the other number will be 2/5 times x, which is 2/5×x or 2x/5

According to the question:

x+(2x/5)=70

=)(5x+2x)/5=70

=)5x+2x=70×5

=)7x= 350

=) x = 350/7

=)x= 50

Therefore 2x/5 = (2×50)/5 = 100/5 = 20

Therefore the numbers are 50 and 20
