MAT Exam 2023 Paper

Question Numbers: 136-140

DIRECTIONS (Qs. 136-140): Go through the pie chart/s given below and answer the question that follows.

The distribution of construction of Solar Power Plant (S.P.P.) in the world in 2024 and the cost incurred in building and maintaining these Solar Power Plants (S.P.P.) in 2024 was tabulated countrywise and drawn in the pie chart.

Total cost incurred in constructing and maintaining (S.P.P) in world in 2024 = $3500 million

Question : 137 of 200

Marks: +1, -0

If USA reduces the construction of Solar Power Plant by 30%, Russia by 35%, UK by 25% and others by 40%, then what will be the total number of Solar Power Plant construction in the world?

92000
78000
84000
Data Insufficient

Solution:

Concept:

The original absolute total number of Solar Power Plants is required; percentage shares alone cannot give the new total after reductions.

Explanation:

The pie chart provides only the percentage distribution of S.P.P. construction among USA, Russia, UK and others.

The original total number of Solar Power Plants constructed in 2024 is not given in the question.

To find the new total, the reductions must be applied on the actual base values:

USA:

30\%

reduction means

0.7 \times \text{USA share}

Russia:

35\%

reduction means

0.65 \times \text{Russia share}

UK:

25\%

reduction means

0.75 \times \text{UK share}

Others:

40\%

reduction means

0.6 \times \text{Others share}

Adding these reduced absolute values would give the new total construction.

Without the original total number of plants, these absolute values cannot be calculated.

Therefore, the data is insufficient to determine the answer.
