Answer 1

Step-by-step explanation:

P = 20000

R=10\% per annum

=5\%6 monthly

Compound interest in 1.5 years if compounded 6 monthly

1.5 years=3^ * 56 months) R=5\% Interest =20000(1+5/100)^ 3 -20000

=3,152.5 Rs

if Compounded Annualy

interest for 1 st year

=20000^ * 10^ * 1/100

= mathcal 200

Now Amount become =20000+2000= 22000

Interest for next 6 months =22000^ * 10^ * (1/2) / 100 = 1100

Interest =2000+1100=3100 Rs

Difference =3152.5-3100= Rs 52.5
