The present age of the mother is 30 years.
<u>Step-by-step explanation</u>:
Step 1 :
At present,
- Age of Jane = x
- Age of Billy = 5x
- Age of mother = 3(5x) = 15x
Step 3 :
After 2 years,
- Age of Jane = x+2
- Age of mother = 8 times as Jane = 8(x+2)
Step 3 :
Age of mother at present + 2 years = Age of mother after 2 years
⇒ 15x + 2 = 8(x+2)
⇒ 15x + 2 = 8x + 16
⇒ 7x = 14
⇒ x = 2
Step 4 :
Substitute x=2,
Age of mother at present = 15x = 30 years.
