Question

Read the information given carefully and answer the question that follows: Automobiles are the most preferred mode of transport because they allow us to cover large distance quickly. resultantly, vehicles have been developed that run on diesel, petrol and even on electricity, which is a remarkable innovative development during a survey about the percentage wise distribution of cars in four different states, the information regarding ratio between the diesel engine cars, petrol engine cars and electric cars was collected. total number of cars for which data was collected was 8000. Of these, State 1 had 15% of the total cars in the ratio of 3:4:1 (diesel, petrol and electri(c); State 2 had 20% of the total cars in the ratio of 5:3:2 (diesel, petrol and electri(c); State 3 had 30% of the total cars in the ratio of 4:5:3 (diesel, petrol and electri(c), and; State 4 had 35% of the total cars in the ratio of 7:5:2 (diesel, petrol and electri(c). If 45% of the electric cars in State 4 are air conditioned (A(c) and remaining are non-AC, what is the number of non-AC cars in the State?

• A. 190
• B. 180
• C. 220
• D. 380
• E. 240

Hint:

Percentage of non-AC = 100% - percentage of AC.

Answer 1

The Correct Option is C

Step 1: From previous calculation: State 4 electric cars = 400.
Step 2: 45% are AC, so 55% are non-AC.
Step 3: Non-AC = $55\% \times 400 = 0.55 \times 400 = 220$.
Step 4: Final Answer: 220.
