Answers and Explanations
Answer 1: (d)
The engine costs 30% of 100000 = Rs30000
The correct option is (d)
Answer 2: (c)
The cost of gear box = 15/100 x 20/100 x 100000 = Rs. 3000
The correct option is (c)
Answer 3: (c)
If the total cost is Rs 100, then the cost of Transmission is Rs 20 and of brakes = 30% of 20 = Rs 6
Hence, brakes constitute 6% of the total cost.
The correct option is (c)
Answer 4: (a)
Cost of the tyre = 15/100 x 20/100 x 100000 = Rs. 3000
If the cost is increased by 25% the price should be increased by ¼ x 3000 = Rs. 750
The correct option is (a).
Answer 5: (b)
The transmission cost is 20% of Rs 100000 = Rs 20000
If the transmission cost is increased by 20% then the new cost will be 20000 × 1.2 = Rs 24000
As the selling price of the car is same as before, so the profit will reduce by 24000 – 20000 = Rs 4000
The correct option is (b)
Answer 6: (d)
The total cost of car to manufacturer is given to be Rs 100000 but the selling price is not given.
Hence,the profit percentage cannot be determined.
Answer 7: (a)
The cost of clutch is 30/100 x 20/100 x 100000 = Rs. 6000
Hence, the required percentage = (6000/100000) x 100 = 6%
Correct option is (a).
Answer 8: (b)
The transmission cost is 20% of 100000 = Rs 20000
The cost of engine = 30% of 100000 = Rs 30000
Now the transmission cost increases by 10%, so new transmission cost = Rs 22000
and similarly, the new engine cost is Rs 36000
Total increase in the cost of car = 2000 + 6000 = Rs 8000
Hence, the new cost of car = Rs 108000
The required percentage = (22000/108000) x 100 = 20.37%
The correct option is (b)
