The value of a machine is Rs 6,250. It decreases by 20% during the first , 40% during the second year and 30% during the third year. What will be the value of the machine after 3 years?
Options: A) Rs 2,100 B) Rs 2,200 C) Rs 2,152 D) Rs 2,252 E) none of these
Here Rs 2,100 = 6250, x = - 20, y = - 40 and z = - 30   Therefore value of the machine after 3 years   = Rs 2,100 ( 1 + x/100) ( 1 + y/100) ( 1 + z/100)   = 6250 ( 1 - 20/100) ( 1 - 40/100) ( 1 - 30/100)   = (6250 x 80 x 60 x 70) / (100 x 100 x 100)   = Rs 2,100   Rs 2,100NSWER:Rs 2,100
