Answer:
8.75%
Step-by-step explanation:
Total Investment is 15000.
Initial investment is 7000.
So remaining Principle is 8000.
7000 at 5% and 15000 at 7%
(7000×5)/100=350 that is SI for Amt 7000.
((15000×7)/100=1050 that is SI for Total Amt 15000.
Total SI Remaining is 1050-350=700 that is the SI for remaining Amt 8000.
So, SI = PNR/100
700= (8000×R)/100
R=(700×100)/8000
R=(70/8)
R=8.75%
So simple!! You Just Understand the Concept!!
