lakhvir present age=7*4=28 yrs
lakhvir age 6 years ago=22 yrs

Answer 2

Given: the ratio of the present age= 5:7

After 8 years Indu's age will be 28.

To find: Lakhvir's age 6 years ago

Step-by-step explanation:

Step 1 of 2

Let the present ages of Indu and Lakhvir be 5x and 7x, respectively.

As,  $\frac{5x}{7x} =\frac{5}{7}$

After 8 years Indu's age will be: 5x+8

According to question, 5x + 8 = 28

Therefore, the value of x can be calculated as:

$5x+8=28\\\\5x=28-8\\\\5x=20\\\\x=20/5\\\\x=4$

Step 2 of 2

Lakhvir's present age will be= 7x = 7 x 4 = 28.

So, 6 years ago his age would have been= 28 - 6 = 22 years.

Lakhvir's age 6 years ago would be 22 years.
