Answer 1

Answer:

a. 2789.1

b. 823.5

Step-by-step explanation:

a. principal(p)=18000

rate(r)=10.33%

time(t)=1.5

simple interest(S.I.)=?

S.I.=p×r×t/100

=18000*1.5*10.33/100

=278910/100

=2789.1 Ans

b. principal(p)=27000

rate(r)=5%

time(t)=0.61

simple interest (S.I.)=?

S.I=p×r×t/100

=27000*5*0.61/100

=82350/100

=823.5 Ans

Answer 2

Answer:

a) 900

b) 810

Step-by-step explanation:

a) p = 18000

t = 1 year 6 months = 1.5 = 15/10

r = 3 1/3 = 10/3

si = 18000×15×10/100×10×3

= 900

b) p = 27000

t = 219 days = 0.6 = 6/10

r = 5

si = 27000×6×5/100×10

= 810
