The following pie-chart shows the expenditure details of a family. If the total expenditure on food is ₹ 4800, then how much is the total expenditure on all the items ?
| Item | Share |
|---|---|
| Food | 30% |
| Rent | 25% |
| Saving | 18% |
| Transport | 12% |
| Retail | 10% |
| Clothes | 5% |
Answer: B
The total expenditure is ₹ 16,000.
Food is 30% of the total, and it amounts to ₹ 4800:
\[ \begin{aligned} 0.30 \times T &= 4800 \\ T &= \frac{4800}{0.30} = 16{,}000 \end{aligned} \]
A quick check: the six shares (30 + 25 + 18 + 12 + 10 + 5) add up to 100%, so the chart covers the whole budget. ₹ 15,000 would make food 32%, and ₹ 18,000 would make it about 26.7%, so neither fits the 30% shown.
