Find the compound am out and compound interest of the following for yearly compounding P=Rs55000,T=2yearly, R=5%

60637.5,5637.5

Explanation:

principle=55000

rate=5%

time= 2 yrs

we know,

C.A= P[(1+R/100)^T]

=55000[(1+5/100)^2]

=55000×1.1025

=60637.5

now,

C.I= P[(1+R/100)^T-1]

=55000[(1+5/100)^2-1]

=55000×0.1025

=5637.5#

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
