  1. 250
  2. 366
  3. 400
  4. 500
  5. 2500

The price of a product is $a. Bill bought s products and then sold 80 percents of them $b. which of the following represents the whole deal if Bill’s profit was three times the cost?

  1. 0.8sb = 4sa.
  2. (1-0.8) s –ab = 3s.
  3. 3(0.8a – sb) = sa.
  4. (s-0.8s) (b-a) = 3.
  5. (s0.8s) / (b-a) = 3.

Answer(s): A

Explanation:

This statement is equivalent to 0.8sb – sa = 3sa. The income is 0.8sb, the cost is sa, so the profit is three times the cost.
The correct answer is A.



A grocer bought 24Kg of coffee beans at price X. After a while one third of the stock got spoiled so he sold the rest for 200$ per Kilo and made a total profit of twice the cost. What must be price X?

  1. 66 2/3$.
  2. 50 1/3$.
  3. 44 4/9$.
  4. 33 1/3$.
  5. 24 1/2$.

Answer(s): C

Explanation:

The total income is 16x200. The cost is 24X, and the total profit is 3200 – 24X = 48X. The correct answer is C.



Kenny is three times older than Bob. In P years he will be twice older than Bob will be Q years later. Which of the following represents Kenny’s age comparing to Bob’s? (If X = Kenny’s age)

  1. X + P = 6X (P+Q).
  2. 2(X+P) = 3X + Q.
  3. (X+P)/2 = X/3 + P + Q.
  4. 3(X+P+Q) = 2X.
  5. 3X = 2(P + Q).

Answer(s): C

Explanation:

X is Kenny’s age. X/3 is Bob’s age. Answer C is equivalent to (X+P) = 2(X/3+P+Q), which means that in P years, X+P is 2 times (X/3+P) plus Q years. The correct answer is C.
