| Total | 74 | 71 | 75 | 90 | 80 | 86 | 476 |
In which year was the total production of cars of types P and Q together equal to the total production of cars of types R and S together?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 1993.
Given that
The sum of cars of types P and Q and of types R and S in 1989 = 8 + 16 and 21 + 4 = 24 and 25 respectively
Similarly for year 1990 = 30 and 23
For 1991 = 30 and 17
For 1992 = 29 and 31
For 1993 = 33 and 33
Hence, for 1993, the total production of cars of types P and Q together equals the total production of cars of types R and S together.
