Question

Rs 5,000 increases to Rs 5,700 in a year. Accordingly, after 5 years, how much will be Rs 7,000 at the same simple interest rate ?​

Answer 1

Answer:

4900 rupees + 7000 rupees = 11900 rupees

Step-by-step explanation:

Rs 5000 to Rs 5700: Rs 700 interest

Which means: Principle = 5700-5000 = 700 rupees.

PTR/ 100 = 5000*R*1/100

5000R/100 = 700

50R= 700

Rate of interest= 14%

Simple interest = PTR/100

Here now principle is Rs 7000, time is 5 years, and rate is 14.

7000*5*14/100

70*5*14= Rs 4900 interest payable after 5 years.

Sum of principle and interest= 7000+4900= 11900 rupees
