Question

ZAKI IS NOW TWICE AS OLD AS OSCAR, TWO YEARS AGO HE WAS THREE TIMES as OLD AS Oscar was, how old are they now? If Zaki is 8years and Oscar is 4years

Answer 1

Let Z be Zaki's age. Oscar's age now is Z/2. Two years ago, Oscar's age was Z/2-2.

Two years ago: Z-2=3(Z/2-2)=3Z/2-6.

Therefore, 6-2=3Z/2-Z=Z/2, so Z/2=4 and Zaki is 8 years old, so Oscar is 4 years old.

Two years ago Zaki was 6 years old and Oscar was 2 years old.
