Answer 1

Answer:

725

Step-by-step explanation:

r=20%

a=700

t=2yrs

a=p+s.i

700=x+s.i

s.i=(700-x)

s.i=(ptr)/100

(700-x)=(20×2×x)/100

(700-x)100=40x

70000-100x=40x

70000=40x+100x

70000=140x

x=70000/140

x=500

second case:-

p for fist case=p for second case

p=500

t=5/2 yrs

r=18%

s.i=ptr/100

=500×5/2×18×1/100

=225

a=p+s.i

a=500+225

a=725

required amount=725
