Answer:
a. Power for 1 lamp = W₁/t₁ = 60/10 = 6W
Power for 5 such lamps(P₁) = 6 X 5 = 30W
b. Power for 1 electric motor(P₂) = W₂/t₂ = 100/1 = 100W
c. Power for 1 fan = W₃/t₃ = 80/8 = 10W
Power for 5 such fans = 10 X 5 = 50W
d. Power of 2 heaters(P₄) = W₄/t₄ = 1500/6 = 250W
e. Power of 1 electric motor(P₅) = W₅/t₅ = 1.5 HP/4 = 1119W/4 = 279.75W
Total energy consumed = P₁t₁ + P₂t₂ + P₃t₃ + P₄t₄ + P₅t₅
= 30X10 + 100X1 + 80X8 + 1500X6 + 279.75X4
= 300 + 100 + 640 + 9000 + 1119
= 11159Wh
Electricity bill per month = 11159 X 2+25 = 11159 X 27 = ₹3,01,293
