Number and color based question

Question: There are different color balls arranged in an order as shown in the below diagram:

     

Answer following questions based on your observation:

  1. Which color is arranged in shape of the letter ‘V’
  2. Which colors have the highest and lowest sum value
  3. What is the sum of all pink colors together
  4. There are how many unique colors in each row

Answer: Let us look at the diagram closely and answer the four questions:

1. We need to identify a shape ‘V’ made from one color. Let us observe each color and see if they are arranged in shape of ‘V’. We will highlight first color RED and keep all other colors dim as shown in the below diagram:

     

Here you can clearly see that the color RED is arranged in the shape of ‘V’. You can try to hide other colors as well and see how they are arranged.

2. We need to identify highest and lowest value of colors. Lets us write down all the colors and add their values as shown below:

RED: 1 + 2 + 3 + 4 + 5 = 15
GREEN: 1 + 2 + 1 + 3 + 4 = 11
BLUE: 1 + 2 + 1 + 2 + 3 = 9
ORANGE: 1 + 3 + 4 + 5 + 1 = 14
PINK: 2 + 3 + 3 + 4 + 5 = 17

From the above calculations, we know clearly that PINK has the highest value whereas BLUE has the least value

3. In this question, we need to identify sum of only PINK colors. We have already calculated sum as 17

4. We need to identify number of colors in each row. A row is a horizontal line from left to right (or left to right). In our diagram there are 5 different rows as shown in the below diagram:

     

As we see that there are five rows in this diagram. Now let us see which are the colors present in each row, for this we will draw a table and map each colors as shown below:

Row Number RED GREEN BLUE ORANGE PINK Sum
Row 1 4
Row 2 2
Row 3 3
Row 4 3
Row 5 3

From the above table we can clearly see the number of unique colors in each row.
