Validate

Solution:

Required ratio

= \frac{\text{Number of students at post-graduate level in } V}{\text{Number of students at under-graduate level in } T}

= \frac{18600 \times \frac{20}{100}}{25400 \times \frac{18}{100}} = \frac{186 \times 20}{254 \times 18}

= \frac{93 \times 10}{127 \times 9} = \frac{31 \times 10}{127 \times 3} = \frac{310}{381} = \frac{77.5 \times 4}{77.5 \times 4.92}

= \frac{4}{4.92} \approx \frac{4}{5} = 4:5
