In a pie chart representing annual farm production costs, the angle of the sector for 'Fertilizers and Chemicals' is $72^\circ$. If the total annual expenditure is Rs. $5,00,000$, calculate the expenditure on fertilizers and chemicals in Rupees.
Answer Key:
100000
Step-by-Step Solution & Explanation
A complete circle has $360^\circ$.
Fraction of expenditure:
$f = \frac{72^\circ}{360^\circ} = \frac{1}{5} = 0.20$
Expenditure:
$E = 0.20 \times 500000 = 1,00,000\text{ Rs}$
