Answer 2

Step-by-step explanation:

(i)2:3:5

Total part=2+3+5=10

Therefore fractional part 2/10:3/10:5/10

Percentage of parts=2/10×100:3/10×100:5/10

Percentage of parts=20%:30%:50%

(ii)Given interest pays by Ajay=750 rupees

Time=2 years

Principal=4500 rupees

Then we know interest=Principal×time/100

Then rate=100×750/2×4500

=8.33%
