Question

The following pie diagram shows the total expenditure (in percentage) incurred by 'X' in one month. Answer the given question based on the pie dragram.

If X decides to save money and reduce expenditure uniformly by 20% on all heads, what would be the CHANGE in the percentage share of Education in the total expenditure incurred by X?

A.

9.38%

B.

0%

C.

7.5%

D.

20%

Correct option is B

Solution:

The percentage share of Education in the total expenditure incurred by X = 37.537.5×80%100100×80%×100%=37.5%\frac{37.5-37.5 \times 80 \%}{100-100 \times 80 \%} \times 100 \%=37.5 \%

The CHANGE in the percentage share of Education in the total expenditure incurred by X = 37.5 - 37.5 = 0%

Since the reduction is being made uniformly across all the sections, the resultant shares in terms of percentage will not change.

Thus, the CHANGE in the percentage share of Education in the total expenditure incurred by X would be 0%.
