Successful start-ups in various industries
What should be the increase in the number (to the nearest integer) of successful start-ups in the industry of Health & Sports, so that its success percentage is the same as that of Education?
Answer & explanation
Correct answer: option 4
Percentage of successful startups in education = \(\frac{520}{1280}\) × 100
= \(\frac{13}{8}\) × 25
= 40.625%
Now , 40.625% of successful startups in sports & health = 40.625% of 1050
= \(\frac{40.625}{100}\) × 1050
= 426.56
So increase in startups = 426.56 - 300 = 126.56
From the options correct ans is 127
