| Years | J | K |
| A | 120 | 50 |
| B | 80 | 60 |
| C | 40 | 120 |
| D | 30 | 100 |
| E | 20 | 70 |
L1 = The total production of car by J in all years.
L2 = The total production of car by K in all years.
What is the value of (L2-L1)?
Answer & explanation
Correct answer: option 1
L1 = The total production of car by J in all years.
= 120 + 80 + 40 + 30 + 20
= 290
L2 = The total production of car by K in all years.
= 50 + 60 + 120 + 100 + 70
= 400
( L2 - L1 ) = 400 - 290 = 110
