Answer 2

$\mathfrak{\huge{\pink{Answer:-}}}$

------------------------------

Total energy is consumed at the month of February is 1.358 kwh.

$\huge{\red{Solution:-}}$

----------------------------------

Given, power of electric bulb is 250W = 0.25Kw

The time bulb is used =5 hrs.

Energy consumed by electric bulb is 0.25 × 5 =1.25 Kwh.

The power of another bulb 6.W = 6Kw

Time bulb is used 4.5 hrs.

Energy cosumed:- 0.027 × 4 =0.108 Kwh

Total energy in month of February is 1.25× 0.108 = 1.358 KWh.
