Question

Huma is twice as old as Chetna. Five years ago her age was three times Chetna's age. What are the present ages of Huma and Chetna respectively?​

Answer 1

Answer:

huma is represented by a & chenta is represented by b

Step-by-step explanation:

A's age = a; B's age = b

∴2b=a...(1);a−5=3(b−5)

⇒a=3b−10...(2)

⇒2b=3b−10

⇒b=10 years

and a=2b=2×10=20 years
