produced 2187 quintals of wheat. What was the yearly produce of wheat to
ago?​

Answer 1

Step-by-step explanation:

Cost Price=9000 , R=5%

Depreciation=

100

R

×CP

After 1 year

Depriciation=

100

5

×9000

=450

After 2 years

Depreciation=

100

5

×8550

=427.5

Total Depreciation =450+427.5=877.5

Hence the statement is True

4.

SOLUTION

It is given that

Present production of wheat = 2187 quintals

Increase in production = 8% p.a.

We know that

Production of wheat 2 years ago = A÷(1+r/100)

n

Substituting the values

=2187÷(27/25)

2

By further calculation

=2187÷(27/25)

2

So we get

= 2187×25/27×25/27

=1875 quintals
