Explanation:

Given 3 tube lights, two fans and a television.

1 tube light consumes power = 40 W

There fore ,3 tube lights consume power = 3 x 40 W= 120 W

3 tube lights are kept on for five hours. So, consumption of power by 3 tube lights.

= 5 x 120 W = 600 W-------(1)

1 fan consumes power = 80 W

Therefore, 2 fans consume power = 2 x 80 W= 160 W 2 fans are kept on for 12 hours. So, consumption of power by 2 fans.

= 12 x 160 W = 1920 W-----------(2)

TV draws power = 60 W

TV is kept on for 5 hours = 5 x 60 W = 300 W---------(3)

Therefore, In One day consumption of power = (1) + (2) + (3)

= 600 W + 1920 W + 300 W

= 2820 W = 2.820 KW

Therefore, Total consumption of power in 30 days at Rs. 3 per KW

= 2.820 x 30 x 3 = Rs. 253.80
