maximum interest rate = 3%

so correct option is A) 3%

Explanation:

given data

investment = $6000

receive = $6180

borrow = $6000

to find out

maximum interest rate bank needs to offer on the loan

solution

we consider here maximum interest rate bank needs to offer is = r

so value of investment will be express here as

value of investment = amount to be borrowed * (1 + r) ... 1

put here value we get rate r

6180 = 6000 * (1 + r)

solve it we get

rate = 0.03

maximum interest rate = 3%

so correct option is A) 3%
