Question

Two years ago the ratio of ramesh and ankur was 6:9 respectively two years hence ratio of their ages will be 9:11 respectively what is the present age of ankur

Answer 1

Two years ago
Ramesh's age = 6x years
Ankur's age = 9x years
After two years from today,
⇒ 81x + 36 = 66x + 44
⇒ 81x – 66x = 44 – 36
⇒ 15x = 8
∴ Ankur's present age
Ans: 6.8years.

Hope it helps!!

Answer 2

Answer:

The present age of ramesh is 5.2 years and the present age of Ankur is 6.8 years

Step-by-step explanation:

Given that,

The ratio of ages of Ramesh and ankur two years ago is 6:9 and

The ratio of ages of Ramesh and ankur two years hence will be 9:11.

Let the present ages of Ramesh amd ankur be x and y respectively.According to the given data,two years ago the ratio is

$\frac{x - 2}{y - 2} = \frac{6}{9} \\ = > 9x - 18 = 6y - 12 \\ = > 9x - 6y - 6 = 0 \\ = > 3x - 2y - 2 = 0 - - > (1)$

Two years hence the ratio is

$\frac{x + 2}{y + 2} = \frac{9}{11} \\ = > 11x + 22 = 9y + 18 \\ = > 11x - 9y + 4 = 0 - - > (2)$

Solving the equations 1 and 2 we get the values as

$x = 5.2 \\ y = 6.8$

Therefore,the present age of ramesh is 5.2 years and the present age of Ankur is 6.8 years
