Answer:
The present ages of Leena and Heena are 35 years and 25 years respectively.
Step-by-step explanation:
Let the present ages of Leena and Heena be 7x and 5x. Ten years later, their ages will become 9x and 7x respectively. That is, 7x + 10 = 9x and 5x + 10 = 7x. Then,
7x + 1 = 9x
7x - 9x = -10
2x = -10
∴x = -10 ÷ -2
=5.
∴7x = 7*5 = 35 and 5x = 5*5 = 25.
