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. The production decreased for Bajra, Jowar and Rice.

b. Production of Bajra in 2009

= 1.4 × 10³ – 100

= 1400 – 100

= 1300

= 1.3 × 10³ hectares

Production of Jowar in 2009

= 1.7 × 10⁶ – 440,000

= 1,700,000 – 440,000

= 1,260,000

= 1.26 × 10⁶ hectares

Production of Rice in 2009

= 3.7 × 10³ – 100

= 3700 – 100

= 3600

= 3.6 × 10³ hectares

Production of Wheat in 2009

= 5.1 × 10⁵ + 190,000

= 510,000 + 190,000

= 700,000

= 7 × 10⁵ hectares

c. Production of Rice in 2015

= (3600 – 600) hectares

= 3000 hectares

= 3.0 × 10³ hectares
