Question

If rs. 4000 becomes rs. 4560 in 2 years at the certain rate of interest, what will rs. 5000 become at the end of 4 years at the same rate of interest under simple interest ?

Answer 1

Answer:

5140

Step-by-step explanation:

In case one the simple interest(SI) for two years is rs.560 i.e(4560-4000).

SI=(P*R*T)/100

560=(4000*R*2)/100

R=7%

For case 2

SI=(5000*7*4)/100

SI=rs.140

The amount becomes 5000+140=rs.5140
