Question

17. In what time simple interest on Rs 500 at the rate 3% per annum is same as the simple interest on Rs 900 for two years at the rate 5% per annum? ​

Answer 1

Answer:

Rs. 1500

Step-by-step explanation:

S.I = P × R × T

100

So,

For first year

900 = 500 × T × 3

100

900 × 100 = T { Transposing and zeros will be cut }

3 × 500

900 = T

3×5

300 = T

5

60 = T

Now, for 2 years

S.I = 500 × 60 × 5 { zeros will be cut }

100

S.I = 5 × 60 × 5

S.I = Rs. 1500
