Explanation:
Step 1
For Ritu,
Principal(P) = Rs 100
Time(T) = 5 year
Rate(R) =8%pa
Intrest (I) = ???
We know,
I = P*T*R /100
= 100*8*5/100
=Rs40
now
For Jitu,
Principal(P) =Rs 100
Rate(R)=9%pa
Time (T) = 4 year
Intrest(I) =?
We have
I = P*T*R/100
=100*4*9/100
=Rs36
Step 2
We have
Intrest of Ritu have more then that of Jitu so she makes more profit
now Profit diffrence =Rs40-Rs36
=Rs4
Therefore Ritu gets 4 more profit then Jitu
