Gita is 12 years older than Harvey. In 4 years, Gita will be twice as old as Harvey. How old will Harvey be in 3 years?
A. 5
B. 11
C. 15
D. 19
E. 23
An alternate approach is to PLUG IN THE ANSWERS, which represent Harvey's age in 3 years.
When the correct answer is plugged in, Gina in 4 years will be twice as old as Harvey.
D: 19, implying that Harvey's current age = 19-3 = 16
Since Gina is 12 years older than Harvey, Gina = 16+12 = 28.
Harvey in 4 years = 16+4 = 20
Gina in 4 years = 28+4 = 32
Since Gina in 4 years is not twice as old as Harvey, eliminate D.
B: 11, implying that Harvey's current age = 11-3 = 8
Since Gina is 12 years older than Harvey, Gina = 8+12 = 20.
Harvey in 4 years = 8+4 = 12
Gina in 4 years = 20+4 = 24
Success!
Gina in 4 years is twice as old as Harvey.
The. correct answer is
B.
