| 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)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 16: 11
L1 = ( 1150 + 850 + 950 + 350 + 250 ) - ( 350 + 550 + 750 + 650 + 450 )
= 3550 - 2750 = 800
L2 = 2750 / 5 = 550
Ratio = 800 : 550 = 16: 11
