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'.
