Answer:Let the money lend by Ravi to Harsh at 4% simple interest be Rsx.
Therefore, money lend by Ravi to Harsh at 6%
simple interest be Rs(3600−x)
as total amount lend is Rs3600.
Now simple intrest at 4% for 5 years
Principal (P)= Rs x, rate(R)=4% and Time (T)=5

Now simple interest at 6% for 5 years
Principal (P)= Rs (3600−x), rate (R)=6% and Time (T)=5
SI=

(108000−30x)
Given that, total simple interest received = Rs 960.
Therefore, 960=

+

(108000−30x)
⇒960×100=20x+108000−30x
⇒96000=108000−10x
⇒10x=108000−96000
⇒10x=12000
∴x=Rs1200
Money lend by Ravi on 4% interest rate is Rs1200.
