reena took a loan of $. 1200 with simple interest for as many years as the rate of interest. if she paid $ 588 as interest at the end of the loan period, what was the rate of interest?
sqrt(divide(multiply(588, const_100), 1200))
"let rate = r % and time = r years . then , 1200 x r x r / 100 = 588 12 r 2 = 588 r 2 = 49 r = 7 . answer : b"
