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.
