A number is (2/5) times another number. If their sum is 70. Find the numbers.

Answer:

Solution:-

Let the required number be x.

Then,

= x + (2x/5) = 70

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

= (7x/5) = 70

Multiplying both side by (5/7)

= (7x/5) × (5/7) = 70 × (5/7)

= x = 50

The other number is (2x/5)

= (2 × 50)/5

= 100/5

= 20

∴the required numbers are 50 and 20
