Question:

The price of an article increases by 20% every year. If the difference between the price at the end of the third year and fourth year is 259.20, then 40% of the price at the end of  the second year ?

Options:

400

412

432

450

Correct Answer:

432

Explanation:

 20% =  \(\frac{1}{5}\)   . let original price = 5   , 

increased price = 5 + 1 = 6

                 I yr         II yr            III yr              IV yr     

                 5         :    6

                                 5         :         6

                                                      5           :      6

----------------------------------------------------------------                                        

overall- 125    :      150      :     180        :   216                                                                              

 ( 216R - 180R) = 36R

36R = 259.2 ( given )

1R = 7.2

40% of the price at the end of  the second year

\(\frac{2}{5}\) × 150R = 60R

60R = 60 × 7.2  = 432
