If he lent total 3600 at 6%
The total interest = 3600 *6*5/100 = 1080

Navdeep gave Rs. 2400 to Amarjeet at 6% interest.
Step-by-step explanation:
Navdeep had a total of Rs. 3600
Let he lend Rs. x at 6% interest and (3600 - x) at 4% interest.
We know SI = PRT/100
where SI = interest
P = Principal
R = Rate
T = Time
We know that the total interest = Rs. 960
=> [tex]\frac{(3600-x)4*5}{100}[/tex] + [tex]\frac{x*6*5}{100}[/tex] = 960
=> [tex]\frac{3600-x}{5}[/tex] + [tex]\frac{3x}{10}[/tex] = 960
=> [tex]\frac{7200-2x+3x}{10}[/tex] = 960
=> 7200 + x = 9600
=> x = 9600 - 7200
=> x = 2400
Therefore, Navdeep gave Rs. 2400 to Amarjeet at 6% interest.
