Answer 2

Answer:

Let the original value be x

Price after 1 year = 90 % of x

= 90x / 100

Price after second year = 90 % of (90x / 100)

= 81x / 100

=> Price will now increase after third year

SO,

Price after third year = 110 % of (81x / 100)

= 110/100 x 81x/100

= (891x / 1000)

This is equal to rs. 40095

=> 891x / 1000 = 40095

=> 891x = 40095 x 1000

=> x = 40095 x 1000 / 891

=> x = 45 x 1000

=> x = Rs. 45000
