Gold

A gold bar balances with nine-tenths of 1 pound and nine-tenths of a similar gold bar. How much does each gold bar weigh?

Answer:

Nine pounds. Examine the objects on the right side of the balance. If we looked at the balance pan containing the two bars, we'd see that one-tenth of the gold bar is absent. In its place we have nine-tenths of a pound. From this we can infer that one-tenth of a gold bar weighs nine-tenths of a pound. Therefore, a complete gold bar would weigh ten times as much. 9/10 pound x 10 = 90/10, or 9 pounds.

Answer:

What is the sum of x, y, and z?

In the multiplication puzzle below, x, y, and z represent different digits. What is the sum of x, y, and z?

Answer:


x = 5, y = 6, and z = 4, so the sum is 15.The variable x can be either 0 or 5. It must be 5 because there is no number that ends in 0 when multiplied by 7 (y * 7, resulting in x).Therefore, a 3 is carried over to the y. Since x is 5, y must be 6 because 7 * 6 = 42. Add the 3 that was carried over and you get 45. Therefore, z is 4.
