Question

A say to her friends, "10 years hence, i will be twice as old as i was 5 years ago". how old is A now?​

Answer 1

Answer:

let A's present age be 'a' years

so according t the question-

10 years hence i.e after 10 years A's age= 2 times her age 5 years back

(a+10)=2(a-5)

a+10=2a-10

2a-a=10+10

a=20

therefore A's present age is "a" years=20 years

hope it helps!
