| Companies | Television | Fridge |
| P | 80 | 100 |
| Q | 70 | 50 |
| R | 60 | 40 |
| S | 50 | 70 |
| T | 90 | 55 |
Which of the following statements is NOT correct?
I. The difference between the average production of television and fridge by R and the average production of television and fridge by S is 10.
II. The production of television and fridge by P is 20% of the production of television by T.
Option 1: Both I and II
Option 2: Neither I nor II
Option 3: Only I
Option 4: Only II
Correct Answer: Only II
Solution :
I.
Average production of television and fridges by R = $\frac{60+40}{2}=50$
Average production of television and fridges by S = $\frac{50+70}{2}=60$
$\therefore$ The difference between both averages = 60 – 50 = 10
Thus, this statement is correct.
II.
The production of television and fridge by P = 80 + 100 = 180
Production of television by T = 90
$\therefore$ Required percentage $=\frac{180}{90}\times100=200$%
The given percentage is 20.
Thus, this statement is NOT correct.
Hence, the correct answer is Only II.
