Answer:

Step-by-step explanation:

sum at the end of second year =  rs 34668.75

sum at the end of third year = rs 37268.90625

                                                    = 37268.90625 - 30000

                                                    = rs. 7268.90625

Answer 2

Answer:

Step-by-step explanation:

Sum of 30000, T= 3yrs , R= 15÷2 %

Now,for 1st yr:

Intrest(I)=P*R*T÷100 =30000*1*15÷3÷100

=300*15÷2= ₹2250

I =₹2250

Now, at the end of 1st year P+I

=30000+2250

=₹32250

=P for 2yr

2 nd yr:

Intr.=P*R*T÷100

=32250*1*15÷100

=241875 ÷ 100

=₹2418.75

Now,at the end of 2nd yr = P + I

= ₹32250 + 2418.75

=₹34668.75
