Answer 2

Answer:

Hey mate.

Here is your answer -

【Ans.(i)】- Mean profit for each crop over 4 years -

Crop- Groundnuts: Profit of each year =

Rs.7000, Rs.8000, Rs.7500, Rs.7500

Mean profit = 【Rs.7500】

\begin{gathered}mean = \: \frac{sum of \: observations}{total \: no. \: of \: observations} \\ mean = \: \frac{rs.7000 + rs.8000 + rs.7500 + rs7500}{4} \\ mean = \: \frac{rs.30000}{4} \\ therefore \: mean = \: rs.7500\end{gathered}

mean=

totalno.ofobservations

sumofobservations

mean=

4

rs.7000+rs.8000+rs.7500+rs7500

mean=

4

rs.30000

thereforemean=rs.7500

Crop- Jawar: Profit each year= Rs.6000, Rs.1000, Rs.8000, Rs.1000

Mean profit= 【Rs.4000】

\begin{gathered}mean = \: \frac{rs.6000 + rs.1000 + rs.8000 + rs.1000}{4} \\ mean = \: \frac{rs.16000}{4} \\ therefore \: mean = \: rs.4000\end{gathered}

mean=

4

rs.6000+rs.1000+rs.8000+rs.1000

mean=

4

rs.16000

thereforemean=rs.4000

Crop- Millets: Profit per year= Rs.9000,Rs.5000,Rs.3000,Rs.4000

Mean profit=【Rs.5250】

\begin{gathered}mean = \: \frac{rs.9000 + rs.5000 + rs.3000 + rs.4000}{4} \\ mean = \: \frac{rs.21000}{4} \\ therefore \: mean = \: rs.5250\end{gathered}

mean=

4

rs.9000+rs.5000+rs.3000+rs.4000

mean=

4

rs.21000

thereforemean=rs.5250

【Ans(ii)】- According to our answer, groundnuts should be cultivated next year.
