Answer:
15,25.
Step-by-step explanation:
Let the numbers be 3x and 5x.
When increased by 10, the numbers becomes (3x+10) and (5x+10).
A/Q,
(3x+10)/(5x+10) = 5/7
Cross - multiplying
→ 7(3x+10) = 5(5x+10)
→ 21x+70 = 25x+50
→ 21x-25x = 50-70
→ -4x = -20
→ x = 20/4
→ x = 5.
Therefore,
numbers are 15 (3x = 3×5) and 25 (5x = 5×5).
Hence, numbers are 15 and 25 respectively.
