Lorna invests $9000, with some at 6% annual interest and some at 11% annual interest. If she receives a total of $580 from these investments at the end of a year, how much was invested at the 6% interest rate? | [
"$160",
"$2,200",
"$1,600",
"$1,800"

Number N is randomly selected from a set of all primes between 10 and 40, inclusive. Number Q is selected from a set of all multiples of 5 between 10 and 40 inclusive. What is the probability that N+Q is odd? | [
"5/8",
"1/2",
"2/3",
"4/7"

A dishonest grocer professes to sell pure butter at cost price, but he mixes it with adulterated fat and thereby gains 20%. Find the percentage of adulterated fat in the mixture assuming that adulterated fat is freely available? | [
