Let the original price be x and sale be ofy units.
Then, the revenue collected initially = x x y
Now, new price = 0.8 x, new sale = 1.8 y
Then, new revenue collected = 1.44 xy
% increase in revenue = ([0.44xy/xy] x 100) = 44% increase

Solution:
Given, the price of the radio was reduced by 20% and its sale increased by 80%.
Let's assume the original price of the radio as Rs. 100.
After a 20% reduction in price, the new price becomes Rs. 80.
Now, the sale increases by 80%.
Therefore, the new sale price will be 80% of the original sale price.
New sale price = 100 + 80 = Rs. 180
Let's calculate the percentage increase in sales:
Percentage increase in sales = (New sale price - Original sale price) / Original sale price x 100
= (180 - 100) / 100 x 100
= 80%
Hence, the net effect on the sale is a 44% increase.
Therefore, option A is the correct answer.

Therefore, the new sale price will be 80% of the original sale price.
New sale price = 100 + 80 = Rs. 180
Let's calculate the percentage increase in sales:
Percentage increase in sales = (New sale price - Original sale price) / Original sale price x 100
= (180 - 100) / 100 x 100
= 80%
Hence, the net effect on the sale is a 44% increase.
Therefore, option A is the correct answer.
