Question

Wheat production increased by 50% to a value of 50 million tons. What is the present wheat production?

  1. 70 million tons    
  2. 60 million tons    
  3. 50 million tons    
  4. 75 million tons    

Hint:

For example Jack got 100 marks out of 100 in a subject, this means in that particular subject Jack got 100%.
Jill got 50 marks out of 100 in the same subject, this means she got 50% which is half of 100%.
Now here original wheat production is 50million tonnes, and is increased by 50% of original wheat production.
present wheat production = original wheat production + 50% of original wheat production.

The correct answer is: 75 million tons


    Original wheat production = 50 million tonnes
    Since the present wheat production is increased by 50%
    This implies New wheat production = original wheat production + 50% of original wheat production.
    New wheat production = left parenthesis 50 space plus space 50 percent sign space o f space 50 right parenthesis m i l l i o n space t o n n e s
 = left parenthesis 50 space plus 50 over 100 cross times 50 right parenthesis m i l l i o n space t o n n e s space equals space left parenthesis 50 space plus 25 right parenthesis m i l l i o n space t o n n e s space equals space 75 m i l l i o n space t o n n e s
    Thus New wheat production is 75 million tonnes.

    Alternatively
    50% increase implies 150 %
    thus ,150% of 50 = 150 over 100 cross times 50 equals 75 space m i l l i o n space t o n n e s
