Monday : The ratio of the total number of purple to green colour balloons manufactured is 3 : 4 and the ratio of the total number of purple to grey colour balloons manufactured is 3 : 2, and the sum of the total number of purple, green and grey colour balloons manufactured is 450. Tuesday : The total number of purple colour balloons manufactured is 37.5% more than the total number of grey colour balloons manufactured and the ratio of the total number of green to grey colour balloons manufactured is 9 : 8.

Answer: Option D — 11 : 5

Detailed Solution

1

On Wednesday purple = 150, which is of green, so green = 150 × 11 ÷ 5 = 330.

2

On Monday purple : green : grey = 3 : 4 : 2 (sum 9), so purple = 450 × 3 ÷ 9 = 150.

3

Ratio = 330 : 150 = 11 : 5.

Data Interpretation — UPSSSC PET Preparation

This question tests your understanding of Data Interpretation, a key topic in the UPSSSC PET Quantitative Aptitude section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.

Data interpretation (DI) questions present data in a table, bar graph, line graph, pie chart or a combination, and ask a set of questions based on it. The questions test calculation skills applied to real-looking data: percentages and percentage change, ratios, averages, growth rates, and comparisons between years or categories. Speed comes from two habits. First, read the chart carefully before answering, including its title, units and scale. Second, approximate wherever the options are far enough apart. Strong percentage and fraction skills (knowing that 1/8 = 12.5% or 1/6 = 16.67%) make most DI calculations quick. For pie charts, remember that a full circle is 360 degrees and each 1% equals 3.6 degrees. In the exam, attempt the DI sets with the cleanest data first. Practise the data interpretation sets below. Each question has a step-by-step solution with approximation shortcuts.
