Directions: The following table shows the production of rice (in million tonnes) of three states over six years. | States | Years | | --- | --- | | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | | A | 5.2 | 5.4 | 5.8 | 6.2 | 6.5 | 6.9 | | B | 3.8 | 4.1 | 4.4 | 4.8 | 5.2 | 5.7 | | C | 4.5 | 5.2 | 5.8 | 6.4 | 6.7 | 7.4 | If the total production in three states in all six years is represented by a pie-chart, then what is the central angle (to the nearest whole number) of the sector representing production in the year 2014?

  1. 61°

  2. 65°

  3. 63°

  4. 59°
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The total production in 2014 across the three states is 6.2 + 4.8 + 6.4 = 17.4 million tonnes. The grand total of production across all six years is 100.0 million tonnes. The central angle for 2014 is therefore (17.4 / 100.0) * 360 degrees = 62.64 degrees, which rounds to 63 degrees.

Multiple choice

Sushma bought 6 tables and 12 chairs for Rs. 12,000. She sold the tables at a profit of 15% and the chairs at a loss of 10%. If her total gain was Rs. 300, then the total cost of the tables was

  1. Rs. 6,000

  2. Rs. 5,000

  3. Rs. 5,400

  4. Rs. 4,800
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let T be the cost of the tables and C be the cost of the chairs, so T + C = 12,000. The profit equation is 0.15T - 0.10C = 300. Solving these equations simultaneously gives the total cost of the tables as Rs. 6,000.
