Question

The given table shows the crop production of a State in the year 2008 and 2009. Observe the table given below and answer the given questions.

Crop	2008 Harvest (Hectare)	Increase/Decrease (Hectare) in 2009
Bajra	1.4 × 103	– 100
Jowar	1.7 × 106	– 440,000
Rice	3.7 × 103	– 100
Wheat	5.1 × 105	+ 190,000

1. For which crop(s) did the production decrease?
2. Write the production of all the crops in 2009 in their standard form.
3. Assuming the same decrease in rice production each year as in 2009, how many acres will be harvested in 2015? Write in standard form.

Answer 1

a. On the basis of given table, bajra, jowar and rice crop's production decreased.

b. The production of all crop in 2009

Bajra = 1.4 × 10³ – 0.1 × 10³ = 1.3 × 10³

Jowar = 1.7 × 10⁶ – 44 × 10⁴

= 1.7 × 10⁶ – 0.44 × 10⁶

= 1.26 × 10⁶

Rice = 3.7 × 10³ – 0.1 × 10³ = 3.6 × 10³

Wheat = 5.1 × 10⁵ + 19 × 10⁴

= 5.1 × 10⁵ + 1.9 × 10⁵

= 7 × 10⁵

c. Incomplete information
