Question

A farmer increases his output of a wheat in his farm every year by 8percent. This year he produced 2187 Quintana of wheat. What was the yearly produce of wheat to years ago

Answer 1

Answer:

Step-by-step explanation:

Let the Present production of wheat be V

Production 2 years ago be W

According to the formula

V=W(1+r/100) ^n

Here r is the rate%

and n is the number of years

Hence, 2187=W×(1+8/100) ^2

2187=W×27/25×27/25

W=2187×25×25/27×27

=1875 quintals

Answer 2

Given :  A farmer's output of wheat grows by 8% every year. In the year  his output was 2187  quintals  

To Find :  output 2 years before

Solution:

Let say Output two year before  =  P  quintals

Rate of increase = 8 %

Time  = 2 Years

Hence Current output   =  P ( 1 + 8/100)²

= P (1.08)²

= 1.1664 P

1.1664 P  =2187

=> P = 1875

Output two year before = 1875 quintals
