What must be in the oven yet can not be baked? Grows in the heat yet shuns the light of day? What sinks in water but rises with air? Looks like sand, but is fine as hair?
When Julian and Penelope met, one was half the others age plus seven years. Ten years later when they married, Penelope was thirty, but this time one was nine tenths the age of the other. How old was Julian? (No fractions or partial years, whole numbers only).
I’m in an elevator with two other people. When it reaches the first floor, one person gets out and six get in. When it reaches the second floor, three people get out and twelve get in. At the third floor, five leave and nine enter. It rises to the fourth floor, one person gets on and the doors close. Suddenly, the elevator cable snaps and the car smashes to the ground. No one survives the fall, yet I’m alive and know exactly how many people go on and off the elevator at every floor. How is this possible?
At a quirky fruit stand, an orange costs 18 cents, a pineapple costs 27 cents and a grape costs 15 cents. Using the same logic, how much does a mango cost?
1 lb = A 2 lbs + A = B 3 lbs = B 4 lbs = A + B 5 lbs + A + B = C 6 lbs + B = C 7 lbs + B = A + C 8 lbs + A = C 9 lbs = C 10 lbs = A + C 11 lbs + A = B + C 12 lbs = B + C 13 lbs = A + B + C 14 lbs + B = D 15 lbs + B = A + D 16 lbs + A = D 17 lbs = D 18 lbs = A + D 19 lbs + A = B + D 20 lbs = B + D 21 lbs = A + B + D 22 lbs + A + B = C + D 23 lbs + B = C + D 24 lbs + B = A + C + D 25 lbs + A = C + D 26 lbs = C + D 27 lbs = A + C + D 28 lbs + A = B + C + D 29 lbs = B + C + D 30 lbs = A + B + C + D
