How many cars assembled by machine C were accepted?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 4950.
The number of cars rejected by machine C = 550
Percentage of cars accepted by machine C = 90%
It means 10% of cars are rejected by machine C
So,
⇒ 10% = 550
⇒ 100% = 550 × 100/10
⇒ 100% = 5500
Total number of cars in machine C = 5500
The number of cars accepted by machine C = 5500 × 90/100 = 55 × 90 = 4950
