Rs. 46500

Rs. 37852

Rs. 31520

Rs. 45210

None of these

Let’s break down the problem:

- In 3 years, the amount = Rs 40,500

- In 6 years, the amount = Rs 46,200

- So, interest for 3 years = 46,200 – 40,500 = Rs 5,700

- Interest for 3 years = Rs 5,700 ? Interest for 1 year = Rs 1,900

- In 3 years, total interest = Rs 5,700

- So, Principal (Sum) = Amount after 3 years – Interest for 3 years

- That is, Principal = 40,500 – 5,700 = Rs 34,800

Now, check the options:

- Option 1: Rs 46,500 ?

- Option 2: Rs 37,852 ?

- Option 3: Rs 31,520 ?

- Option 4: Rs 45,210 ?
