Question

The cost of three components A, B and C of an electronic machine worth ₹12,000 in 2020 is given in a Pie-chart (Angles: A = $90^\circ$, B = $120^\circ$, C = $150^\circ$). In the following year, the cost of these three components A, B, and C increased by 10%, 20%, and 10% respectively. The cost of the three components A, B, and C respectively in 2021, was:

Accepted Answer

B. In 2020: Component A = $\frac{90}{360} 	imes 12000 = 3000$ Component B = $\frac{120}{360} 	imes 12000 = 4000$ Component C = $\frac{150}{360} 	imes 12000 = 5000$ In 2021: A = $3000 	imes 1.1 = 3300$ B = $4000 	imes 1.2 = 4800$ C = $5000 	imes 1.1 = 5500$.
