The present age of two persons A and B are 40 and 60 years respectively. If after t years the ratio of their age will be 5 : 7. Then the value of t is : |
10 years 20 years 18 years 12 years |
10 years |
ATQ, ⇒ \(\frac{40\;+\;t}{60\;+\;t}\) = \(\frac{5}{7}\) ⇒ 280 + 7t = 300 + 5t ⇒ 2t = 20 ⇒ t = 10 years |
