The ratio between the present ages of Radha and Seema is 5:7. After 8 ...
The correct option is E.
Let the present age of Radha be 5x So 8 yrs back , i.e, at present she is 20.
this means 5x = 20 => x = 4
Then Seema 's age = 7x = 7*4 = 28yrs.
Five yrs ago , her age was 28 - 5 = 23yrs.

The ratio between the present ages of Radha and Seema is 5:7. After 8 ...
Let's assume that the present ages of Radha and Seema are 5x and 7x respectively.
After 8 years, Radha's age will be 28 years. So, we can write the equation as:
5x + 8 = 28
Simplifying the equation, we have:
5x = 20
Dividing both sides by 5, we get:
x = 4
Therefore, Radha's present age is 5x = 5 * 4 = 20 years.
To find Seema's age 5 years ago, we need to subtract 5 from her present age. Seema's present age is 7x = 7 * 4 = 28 years.
So, Seema's age 5 years ago would be:
28 - 5 = 23 years
Hence, the correct answer is option E) None of these because none of the given options matches the calculated age of Seema 5 years ago (which is 23 years).
