Problema Solution
Sana is senior to Mona by 18 years. After 6 years Sana will be twice as old as Mona. Find Mona's presents age?
Answer provided by our tutors
Let 'm' represent Mona's present age.
Then Sana's age can be expressed as: m + 18 (since she is 18 years older than Mona).
After 6 years Mona will be: m + 6 years old.
After 6 years Sana will be: m + 18 + 6 = m + 24 years old.
m + 24 = 2(m + 6)
