Question

The present age of Ram and Rohon are in the ratio 4:5 . Four years later, their age wiĺ be in the ratio 6:5. What are the present ages ?

Answer 1

Answer:

Present age of Ram = 16 years

Present age of rohon = 20 Years

Step-by-step explanation:

Let say present age of Ram = 4x

then present age of Rohon = 5x

After 4 years Age of Ram would be = 4x + 4

After 4 years age of Rohon would be = 5x + 4

after years ratio of their ages = 6:5

it means

$\frac{4x+4}{5x+4} = \frac{6}{5}$

=>20x + 20 = 30x + 25

=>-10x = 5

=> x = -1/2

x can not be negative so data is wrong

Lets assume 6:5 is actually 5:6

$\frac{4x+4}{5x+4} = \frac{5}{6}$

=> 24x + 24 = 25x + 20

=> 4 = x

Present age of Ram = 4*4 = 16 years

Present age of rohon = 5*4 = 20 Years
