There are 111 balls of four different colors in a box. Suppose that if 100 balls are taken then at least one ball of each color appears among the taken balls. What is the minimum number of balls that must be taken so that at least three different colors appear among the taken balls?

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
