when the price of product was decrease by 10%, the number sold increased by 30% what was the increase on the total revenue.
Answer :
Let Price of the product = Rs 100
So,
Price of the product after decrease of 10% = 100 - 10% of 100 = 100 - = 100 - 10 = Rs 90
Let he sold total number of product = 100
So,
Total number of product he sold after increase of 30% = 100 + 30%of100 = 100 + = 100 + 30 = 130
He gets before any decrease of price and increase in number of product sold = 100 100 = Rs 10,000
Now he gets = 90 130 = Rs 11,700
So total gain in revenue = 11,700 - 10,000 = Rs 1700
SO,
Total revenue increase = = 17%
So,
Revenue increase by 17% ( Ans )
Let Price of the product = Rs 100
So,
Price of the product after decrease of 10% = 100 - 10% of 100 = 100 - = 100 - 10 = Rs 90
Let he sold total number of product = 100
So,
Total number of product he sold after increase of 30% = 100 + 30%of100 = 100 + = 100 + 30 = 130
He gets before any decrease of price and increase in number of product sold = 100 100 = Rs 10,000
Now he gets = 90 130 = Rs 11,700
So total gain in revenue = 11,700 - 10,000 = Rs 1700
SO,
Total revenue increase = = 17%
So,
Revenue increase by 17% ( Ans )
