(c) 19 : 16 : 25

(d) 6 : 5 : 1

(b) 6 : 1 : 21

(c) 30: 16: 21

(d) Cannot be determined

(a) 1997

(b) 2000

(c) 1999

(d) 1996

### Answers and Explanations

**Answer 1: (a)**We have to check for those years where total value of production of scooter and bikes < value of car. By observation we can see that in the year 2000, the total production of cars was 860000 and the total production of scooters and bikes was 760000. Hence in 2000, the production of cars was more than 50% of the total production. Correct option is (a)

**Answer 2: (c)** We have

Total= 57600 + 120000 + 40000 = 217600

Correct option is (c)

**Answer 3: (b)** We have

Ratio: 134400 : 210000 : 159600 or 16: 25: 19.

Correct option is (b)

**Answer 4: (c)** We have We have
The ratio of cars: scooters: motorbikes = 225000 :240000 : 210000 = 225:240:210 = 45:48:42
or 15: 16: 14

The ratio of export prices of cars: scooters: motorbikes = 2:1:1.5

The ratio of export earnings of cars: scooters: motorbikes = 15 × 2: 16 × 1: 14 × 1.5 = 30: 16: 21

Option (c) is correct.

**Answer 5: (a)** Keep in mind: You don’t need to calculate for all the years. Calculations should be done for the years which are given in the options, since, ultimately one of them is the answer. The years which are marked as bold in the column are only to be calculated.

It can be clearly observed that in 1997 the motorbike production is 560000 which is 40% of the total production. Therefore, (a) is the correct option.
