Explanation:
Let the amount of electricity produced last month be P.
Let the amount of electricity consumed last month be C.
Since the ratio of electricity produced to electricity consumed was 99:1, P / C = 99 (Equation I)
We need to find whether the value P can be determined.
Statement (1)
P – C = 490,000 (Equation II)
From Equation I and Equation II, we have 2 equations with 2 unknown variables that can be solved to determine the value of P. Hence, Statement (1) is sufficient.
Statement (2)
C = 5,000 (Equation III)
From Equation I and Equation III, we have 2 equations with 2 unknown variables that can be solved to determine the value of P. Hence, Statement (2) is sufficient.
D is the correct answer choice.
