A large field of 700 hectares is divided into two parts. The difference of the areas of the two parts is one-fifth of the average of the two areas. What is the area of the smaller part in hectares?

Correct Answer: 315

Explanation:

Let the areas of the two parts be x and (700-x) hectares


therefore,  x - 700 - x = 1 5 x + 700 - x 2


  2 x - 700 = 70


  x = 385


So, the two parts are 385 and 315.


 Hence, Area of the smaller = 315 hectares
