Correct Answer: $26:9$


Solution : Given: Ratio of blue and yellow colours = 4 : 3
In the upper half, blue : yellow = 2 : 3
Let the total quantity of blue and yellow be 70 units.
The ratio of blue and yellow colours = 40 : 30
Upper half = lower half = 35 units
Quantity of blue in upper half part = 35 × $\frac{2}{5}$ = 14 units
Quantity of yellow in upper half part = 35 × $\frac{3}{5}$ = 21 units
Quantity of blue in lower half part = (40 – 14) = 26 units
Quantity of yellow in lower half part = (30 – 21) = 9 units
So, the ratio of blue and yellow in the lower half = 26 : 9
Hence, the correct answer is 26 : 9.
