Question

Ellee is three times older than Yogesh. Zaheer is half the age of Wahida. Yogesh is older than Zaheer,

Which of the following information will be sufficient to estimate Ellee’s age?

• A. Zaheer is 10 years old
• B. Yogesh is older than Zaheer by 5 years.
• C. Both (a) and (b) above
• D. Data insufficient

Answer 1

The correct option is C Both (a) and (b) above

Z=10 will not enable anyone to estimate Ellee’s age. Y=Z+5 will not give value of Y, which is required to estimate the age of Ellee. If both (a) and (b) are true, then Y=Z+5 and Z=10
$\therefore Y=15$ Thus, the age of Ellee would be exactly known.
