In a box, there are several balls. The pie-chart shows the percentage-wise distribution of 6 different colours of balls; and total number of balls = 1000. Also, the ratio of the light and dark shades of the six colours of balls is given.

What is the total number of green balls?
  1. 180
  2. 170
  3. 185
  4. 190

Answer and explanation

Correct answer: A - 180
Green = 18% of 1000 = 180. The light : dark ratio of 1 : 3 splits these into 45 light and 135 dark balls; the total counts both shades.
