Linear Equations

A cow costs more than 4 goats but less than 5 goats. If a goat costs between Rs. 600 and Rs. 800, which of the following is a most valid conclusion?

  1. A cow costs between Rs. 2,600 and Rs. 3,800.
  2. A cow costs less than Rs. 3,600.
  3. A cow costs more than Rs. 2,500.
  4. A cow costs between Rs. 2,400 and Rs. 4,000.

Answer

Minimum possible cost of cow = 4 × 600 = 2400

Maximum possible cost of cow = 5 × 800 = 4000

The correct option is D.
