At a florist shop on a certain day, all corsages sold for either $20 or $30. If 8 of the corsages that sold for $30 had instead sold for $20, then the store's revenue from corsages that day would have been reduced by 10 percent. What was the store's actual revenue from corsages that day? | [
"$800",
"$600",

Find the value of a/b + b/a, if a and b are the roots of the quadratic equation x2 + 10x +5 = 0? | [
"42",
"6",

] | D | a/b + b/a = (a2 + b2)/ab = (a2 + b2 + a + b)/ab

a + b = -10/1 = -10
ab = 5/1 = 5
Hence a/b + b/a = [(-10)2 - 2(5)]/5 = 90/5 = 18.

x + (x × 2 × 5⁄100) = y + (y × 3 × 5⁄100)

⇒ 11x⁄10 = 23y⁄20 = 6z⁄5 = k ⇒ x = 10k⁄11, y = 20k⁄23, z = 5k⁄6
But x + y + z = 2379.

When we divide 1,043,504,000 by 1000, we get 1,043,504,000 = 1,043,504 * 5^3 *2^3.
1,043,504 is not divisible by 5, thus there are 3 widgets.
