Question

A MACHINE DEPRICIATES EACH YEAR AT 8% OF ITS VALUE IN THE BEGINNING OF THE YEAR . IF ITS VALUE BE ₹ 57500 AT THE END OF THE YEAR 2015,FIND:
1)its value at the end of the year 2014
2) its value at the end of year 2016​

Answer 1

Answer:

1)62500

2)52900

Step-by-step explanation:

The value of machine depreciates 8 percent every year.

1)It is given at the end of 2015 its value is 57500.

This means that 57500 is value after 8percent depreciation at the start of 2015.

i.e., 92 percent is 57500. Then if we find 100 percent we can get the value of machine in 2014.

92---->57500

100--->62500.(since 57500/92=625 and then cross multiply with 100)or[( 57500*100/92)=62500]

2)Now to find the value of machine in 2016

Assume 2015's value as 100 percent and find 92 percent of it..since the value depreciates 8percent every year.

100--->57500

92--->52900.[(57500*92)/100]

Therefore the value of machine at end of 2014 is 62500 and at the end of 2016 is 52900.
