People who liked donut = 26

People who liked cupcakes = 26

From the above venn Diagram, we have

⇒ 50 = 17 – x + x + 8 + 3 + 9 – x + 9 + 6 + 5

⇒ 50 = 17 + 8 + 3 + 9 + 9 + 6 + 5 - x

⇒ 50 = 57 - x

⇒ x = 57 - 50

⇒ x = 7

⇒ 7

Study the following information and select appropriate logical conclusion based on it. The Consumer Pyramids Household Survey quantifies the sharp fall in the rate of growth of jobs for the better educated in recent years. Over the last three years - between early 2016 and late 2018 -38 million jobs were added for people who completed only primary education, that is up to 5th standard. This implied that jobs for these barely educated people increased by nearly 45% over these three years. In comparison, people who had acquired a little better education that is between 6th and 9th standard, saw an addition of much lesser 18 million jobs implying also a lower 26% increase in jobs for these people. People who had completed secondary-to-higher secondary school education - 10th, 11th or 12th - saw a growth of 13 million jobs reflecting only a 12% growth over a three years period.?
