In a colored picture of blue and yellow color, blue and yellow color is used in the ratio of 4 : 3 respectively. If in the upper half, half blue : yellow is 2 : 3, then in the lower half blue : yellow is =?

Answer: Option C

Given, blue and yellow color ratio = 4 : 3 and half part blue and yello ratio = 2 : 3

Let 700 be the painting part in total
∴ Blue part will be: $$\frac{\text{4}}{7}\times 700$$   = 400
And yellow will be: $$\frac{\text{3}}{7}\times 700$$   = 300
Now, upper half part i.e $$\frac{700}{2}$$ = 350
Blue in upper half part → $$\frac{\text{2}}{5}\times 350$$   = 140
And, Yellow in upper half part → $$\frac{\text{3}}{5}\times 350$$   = 210
Remaining half Blue in lower part → 400 - 140 = 260
Remaining half yellow in lower part → 300 - 90 = 210
Ratio of blue and yellow → 260 : 90
⇒ 26 : 9
