Question

Two persons A & B bought land for Rs 2 lac and Flat for Rs 2.2 Lac respectively, The price of the flat rises by 10% and that of land rises by 20% every year. If they exchange there assets after 2 year find the % profit of the gainer.

Answer 1

  price of land = Rs. 2,00,000
 
price increases by 20% i.e.          2,00,000 x 20/100 = Rs. 40,000
                 which becomes =  2,00,000 + 40,000 = Rs. 2,40,000 

 again increases by 10% i.e. = 2,40,000 x 20/100= Rs. 48,000
      which becomes =  2,40,000 + 48,000 =Rs.  2,88,000

now price of flat = Rs. 2,20,000

      each increases by 10% i.e. = 2,20,000 x 10/100 = Rs. 22,000
               which becomes  =  2,20,000 +22,000 = Rs. 2,42,000

again increases by 20% i.e. =  2,42,000 x 10/100 = Rs. 24,200                               which becomes =  2,42,000 + 24,200 = Rs. 2,66,200

now they exchanged their possessions= 

 so profit gonna be  =  288000 - 266200 = Rs. 21800

profit % =  21800/ 266200 x 100 = 8.189


hope u'll get it ..............doubts, ask?
