Answer & Explanation

S1. Ans.(c)
Sol. Use the second bar chart. It is a visual inspection solution.
S3. Ans.(d)
Sol. Mohit’s earning due to the Central zone during 2001 = 20000 * 0.3 = 6000
Mohit’s earning due to the East zone during 2000 = 10000 * 0.3 = 3000
Required Difference = 6000 – 3000 = 3000
S4. Ans.(d)
Sol. Maximum quarterly zonal earnings are for central Region during quarter III, 2002 = Rs. 18000
Minimum quarterly zonal earnings are East Region during quarter II, 2000 = Rs. 500
Hence, Maximum difference = 18000 – 500 = Rs. 17500
Earning in South Region in 2001 
= 20000 × 0.2 + 10000 × 0.2 + 20000 × 0.3 = Rs. 12000
Earning in South Region in 2000 
= 10000 × 0.2 + 5000 × 0.2 + 25000 × 0.3 = Rs. 10500
Therefore, percentage change = 1500/10500 * 100 14.28%
