The table given below shows the production of five companies in two years.
| Years | ||
| Company | Y1 | Y2 |
| A | 50 | 100 |
| B | 90 | 120 |
| C | 30 | 80 |
| D | 80 | 50 |
| E | 20 | 40 |
J1 = The average production of A in year Y1 and Y2.
J2 = Sum of production of B, C and D in year Y1 and Y2.
What is the value of (J2/J1)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 6.
Calculations:
J1 = (100 + 50)/2 = 75
J2 = 90 + 120 + 30 + 80 + 80 + 50 = 450
Hence, the value = (J2/J1) = 450/75 = 6
