Question : The table given below shows the production of five companies in two years.
| Company | Years | |
| L | M | |
| P | 150 | 200 |
| Q | 190 | 220 |
| R | 130 | 180 |
| S | 180 | 150 |
| T | 120 | 140 |
Which of the following statements is NOT correct?
I. The average production of P, Q, R, and S in year L is 172.5.
II. The ratio of the production of T in year L to the production of T in year M is 6 : 7.
Option 1: Only I
Option 2: Both I and II
Option 3: Neither I nor II
Option 4: Only II
Correct Answer: Only I
Solution :
Let's analyze the given information:
1. The average production of P, Q, R, and S in year L:
Average $=\frac{150+190+130+180}{4}=\frac{650}{4}=162.5$
So, statement I is not correct. The correct average is 162.5, not 172.5.
2. The ratio of the production of T in year L to the production of T in year M:
Ratio $=\frac{120}{140} = \frac{6}{7}$ i.e. 6 : 7
So, statement II is correct.
Therefore, the statement that is NOT correct is Statement I.
Hence, the correct answer is 'Only I'.
