Question

rupees 7000 left in bank for 10 yrs at simple interest amount to rupees 9800 what would it amount to after another 5 yrs at the same rate

Answer 1

SI for 10 years =9800-7000=2800
SI for 5 years =2800/2=1400
Total amount =7000+1400=8400

Answer 2

Given

P=7000
T=10yr
AMOUNT =9800
Si=Amount -principal

=9800-7000
=2800

As we know simple interest of every yr is equal

So Si of 5 yr =2800/2=1400

Or 1 yr si=2800/10=280
Then Si of 5yr =280x5=1400

Then amount after another 5 yr

=9800+1400=₹11200

This is ur answer hope it will help you
