DIRECTIONS for questions 5 to 7:Study the following line graphs which show the production (in '0000 units) and percentage exports of scooters, motorbikes and cars respectively over the years.
Data Interpretation Practice Questions

In which of the following years was the production of cars more than 50% of the total production?

1. 2000

2. 2001

3. 1998

4. None of these

Answer Key: 4
Explanation: For 2000, total production is (34 + 42 + 86)0000 = 1620000 units.
Production of cars in 2000 = 420000. Percentage is less than 50%.
For 2001, total production is (26 + 34 + 60)0000 = 1200000 units.
Production of cars in 2001 = 260000. Percentage is less than 50%.
For 1998, total production is (60 + 75 + 84)0000 = 2190000 units.
Production of cars in 1998 = 840000. Percentage is less than 50%.
Hence answer is none of these. Hence 4th option.
Find the total number of automobiles exported in the year 1999.

1. 227600

2. 207600

3. 217600

4. 220000

Answer Key: 3
Explanation: Number of cars exported = 400000 × 0.1 = 40000.
Number of scooters exported = 480000 × 0.12 = 57600
Number of Motorbikes exported = 600000 × 0.2 = 120000
Total automobiles exported = 120000 + 57600 + 40000 = 217600. Hence 3 rd option.
