Jims uncle is 4 times as old as his nephew Jim. In 10 years, Jim's uncle's age will be 20 years more than twice jims age. How old is his uncle right now?
Answer provided by our tutors
Let Jims present age=x years. So, his uncle present age=4x.
After 10 years.
2(x+10)+20= 4x+10
2x+20+20=4x+10
-2x=-30
x=15
Jims's uncle present age=4*15=60 years.
