Q.

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?

View Answer

Correct choice: A

Explanation:

Let the areas of the two parts be x and (700-x) hectares therefore, [x−(700−x)]=15[x+(700−x)2] ⇒2x−700=70 ⇒x=385 So, the two parts are 385 and 315. Hence, Area of the smaller = 315 hectares
