(E) None of these​

Answer 1

Step-by-step explanation:

simple interest =

$\frac{p \times r \times t}{100}$

p= 720 r= 5 t= 5/2

$\frac{720 \times 5 \times 5}{100 \times 5} = 36$

Amount = SI+P

36+720= 756 Answer

Answer 2

Answer:

SI=PTR/100

2 YEARS 6 MONTH'S MEANS 2.5 YEARS

SI= 5*720*2.5/100

SI=90

AMOUNT = SI+ PRINCIPAL

AMOUNT = 90+720=810
