Question

What is the value of 10 percent of y ?
(1) 5 percent of y is 60.
(2) y is 80 percent of 1,500.

• A. Statement I alone is sufficient to answer the problem.
• B. Statement II alone is sufficient to answer the problem.
  
• C. Statement I and II both are needed.
• D. Either of the statements I or II both is sufficient.
• E. Statement I and II both are not sufficient.

Answer 1

The correct option is D Either of the statements I or II both is sufficient.

Arithmetic Percents

This problem can be solved by determining the value of y.

(1) If 5 percent of y is 60, then 0.05 y = 60 and

$y=\frac{60}{0.05}=1,200$; SUFFICIENT.

(2) If Y is 80 percent of 1,500, then y = (0.80)(1,500) = 1,200; SUFFICIENT.

The correct answer is D; each statement alone is sufficient.
