Guys,

I need help in solving below question. I dont have that answer.

There are n Apples in a bag and it cost $p per bag. What is the percentage change in price per bag if Apples are doubled in a bag and price per bag is increased 10%?

a) 10% decrease

b)10% increase

c)20% increase

d)20% decrease

e) cannot determine

Thanks

I think the question is wrongly phrased. From the question clearly %increase in the price of the bag is 10%, irrespective of the number of apples.

I hope this is not the correct intention of this question. If we rephrase the question to consider apple also, the question will be like this-

"There are n Apples in a bag and it cost $p per

apple. What is the percentage change in price per bag if Apples are doubled in a bag and price per

apple is increased 10%?

a) 10% decrease

b)10% increase

c)20% increase

d)20% decrease

e) cannot determine"

This such case answer is like this-

Initial cost of a bag = np

Final cost of bag = 2n*1.1*p =2.2 np

So, the percentage increase in the price per bag=

(2.2np-np)*100 / np =

120 % _________________
