Answer 1

40% of the price at the end of second year is: Rs 432

Step-by-step explanation:

Let say Price at end of third year = P

then price at end of 4th year = P + (20/100)P = 1.2P

1.2P - P  = 0.2P

0.2P = 259.2

=> P = 1296

Price at end of 3rd year = 1296

Price at end of 2nd Year  =  A

A + (20/100)A = 1296

=> 1.2A = 1296

=> A = 1080

40% of 1080 = (40/100)1080 = 432 Rs

40% of the price at the end of second year is: Rs 432
