Question

Amman is 3 times Arun's age and Asha is 2/3 of Amman's age 7 years ago the ratio of ages of Amman and Asha was 2/1, find their present ages.

Answer 1

Answer:

Step-by-step explanation:

Let Arun's present age = x years

so, Amman's present age will be 3x years

so, Asha's present age will be 2/3 × 3x = 2x years

ATQ

7 years ago the ratio of ages of Amman and Asha was 2:1

$\frac{(3x - 7)}{(2x - 7)} = \frac{2}{1} \\ \\ 3x - 7 = 2(2x - 7) \\ \\ 3x - 7 = 4x - 14 \\ \\ - 7 + 14 = 4x - 3x \\ \\ x = 7$

So, present age of Arun will be 7 years

present age of Amman will be 3×7 = 21 years

present age of Asha will be 2×7 = 14 years

Hope my answer will help you much better

Answer 2

Let's Aman's Age be x

Let asha's age be 2/3 x

7 years ago there ages would be

(X - 7)/(2/3 x) = 2/1

Solve the eq and you will get the value of x .. n then from that you can find out their ages

Hope it helps ;-;
