The cost of the components X, Y, Z of a machine worth Rs. 24,000 in 2008 is given as Pie Chart. In the…

In 2008 (total Rs. 24,000), the sector angles $X = 90^\circ$, $Y = 120^\circ$, and $Z = 150^\circ$ give initial costs of $X = \text{Rs. } 6{,}000$, $Y = \text{Rs. } 8{,}000$, and $Z = \text{Rs. } 10{,}000$. Increasing these by 10%, 20%, and 10% in 2009 yields $X = 6{,}000 \times 1.10 = \text{Rs. } 6{,}600$, $Y = 8{,}000 \times 1.20 = \text{Rs. } 9{,}600$, and $Z = 10{,}000 \times 1.10 = \text{Rs. } 11{,}000$.
