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∘90^\circ, B = 120∘120^\circ, C = 150∘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:

  1. A.

    ₹3,300, ₹4,950, ₹5,350

  2. B.

    ₹3,300, ₹4,800, ₹5,500

  3. C.

    ₹3,200, ₹4,700, ₹5,600

  4. D.

    ₹3,600, ₹4,800, ₹5,600

Answer

B

Explanation

In 2020: Component A = 90360×12000=3000\frac{90}{360} \times 12000 = 3000 Component B = 120360×12000=4000\frac{120}{360} \times 12000 = 4000 Component C = 150360×12000=5000\frac{150}{360} \times 12000 = 5000

In 2021: A = 3000×1.1=33003000 \times 1.1 = 3300 B = 4000×1.2=48004000 \times 1.2 = 4800 C = 5000×1.1=55005000 \times 1.1 = 5500.
