Answer 1

Answer:

500

Step-by-step explanation:

Given Radha lent a certain sum of money at 4% per annum and in 8 years the interest amounted to rs 340 less than the sum lent, to find the sum she lent.

Let the sum be x, then amount is Rs 340 less so it will be x - 340.

We have t = 8 yrs , r = 4%

We know that SI = P x R x T /100

                        x - 340 = x x 4 x 8 / 100

                        x - 340 = 32 x / 100

                        x = 32 x / 100 + 340

                    100 x = 34,000 + 32 x

                     68 x = 34,000

                      x = 34,000 / 68

                       x = rs 500

So Radha lent a sum of rs 500
