1. Kelynn is 5 times as old as Janet this year.

Janet is 9 years old now. In how many years' time

will Kelynn's age be twice that of Janet?

2. Don had 4 times as much money as Mei Mei.

After he gave \$9 to Mei Mei and spent \$15, Don and

Mei Mei had the same amount of money, how much money did

Don have at first?

3. Timothy and Claire had \$672 altogether. When Timothy gave

Claire \$35, Claire had 6 times as much money as Timothy. How

much more money had Claire than Timothy at first?

Kelynn----- 9x5=45
total-------45+9=54
54/2=27
In 27 years time,Kelynn's age will be twice of Janet.

Check:
janet:27+9=36
Kelynn:45+27=72
2 times of 36 is 72
