Indian Economy - Understanding the basics of Indian economic system

When the price of fans was reduced by 20%, the number of fans sold increased by 40%. What was the effect on the sale ?

12% increase

12% decrease

30% increase

40% increase

Where we talk about P*Q = R form, there the net change

can be given by (A + B + AB/100)%

= [- 20 + 40 + (- 20)(40)/100]% = (20 - 8) = 12%

Since it is a positive value, that means the sale will be increased by 12%.
