Question

Answer 1

kamya's present age=(6×7×1)/(36-35) =42

Answer 2

Answer: 42 years

Step-by-step explanation:

Let Rani's Present age be 5a ,

And Kamya's Present age be 6a

7 years hence,

Ratio = 6 / 7

(5a+7) / (6a+7) = 6/7

By cross multiplication,

(5a+7) * 7 = (6a+7) * 6

35a+49 = 36a+42

36a-35a = 49-42

a=7

Rani's present age = 5a= 5*7 =35 Years

Kamya 's present age = 6a = 6*7 = 42 years
