2) If the price of the commodity decreases by r% them percentage increase in

Question 2: If the price of sugar falls down by 10% ,by how much percent must a householder increase its consumption , so as not  to decrease expenditure in this item ?

3) In the reduction of x%

the reduction of x%euables a person to by y Kg more for A, then the reduced price and original price Calculation.

Question: A reduction of 10% in the price enables a person to buy 2 kg more wheat for Rs 30.Find the reduced and the original price of wheat.

Solution:

•Reduced Price = (x/100y)A

•{(30 x 10)/(100 x 2)} Rs. = Rs. 3/2

•Original Price = [x/{(100-x)y}] x  A

•[(30 x 10)/{(100 – 10)x2}] = Rs. 5/3

4) Successive profitloss

Question 4: A sells an item at a profit of 20% to B and B sells it to C at a profit of 10%. Find the resultant profit percent .

Solution: 

•When there are two successive profit of x% and y%,net profit percentage

•= {x+y+(xy/100)}

•= 20+ 10 + {(20 x 10)/100} = 32%
