Answer:
315kwh
Explanation:
given, no. of bulbs, n=10
power, p=60w
hour, h=5hr
we know 1KW=1000w,
power consumed by bulbs(P1)= n*p*h
= 10*60*5
=3000Wh
=3KWh
now for heater power consumed (P2)= p*h (no. of heater is 1)
=1500*5
=7500wh
=7.5kwh
power consumed for a month, P= 30(p1+p2)
=30(3+7.5)
=315KWh
hope u get this.
