In a colored picture of blue and yellow color, blue and yellow color is used in the ratio of 4 : 3 respectively. |
Suppose total quantity of blue and yellow color in the picture = 70 units (Since the ratio is 4 : 3)
|
|
So, Upper and Lower part = 70/2 = 35 units |
Now, Quantity of blue in upper part = 35 × (2/5) = 14 units Quantity of blue in lower part = 40 – 14 = 26 units And Quantity of yellow in upper part = 35 × (3/5) = 21 Quantity of yellow in lower part = 30 – 21 = 9 Hence, Ratio of blue to yellow in the lower half = 26 : 9 |
