The table given below shows the sales of two companies in 5 years.
| Companies | ||
| Years | A | B |
| P | 350 | 1150 |
| Q | 550 | 850 |
| R | 750 | 950 |
| S | 650 | 350 |
| T | 450 | 250 |
L1 = The difference between the total sales of A and B in all years.
L2 = The value of average sales of A in all years.
What is the value of (L1 : L2) ?
Answer & explanation
Correct answer: option 3
L1 = The difference between the total sales of A and B in all years
Total sale of A - Total sale of B
= (350+550+750+650+450) - (1150+850+950+350+250)
= 2750 - 3550
= - 800
= 800 ( difference of sale is always positive )
L2 = The value of average sales of A in all years
Average of sale of A = \(\frac{2750}{5}\) = 550
Now , L1 : L2 = 800 : 550
= 16 : 11
