#LRDIoftheDay #9
Mr. WB being the shrewd investor he is, had planned to invest in a few companies across various sectors on 26th September 2016. He selected the best performing two companies from each of IT, Automobile and Banking for this plan. While he was successful at the end of it, he was pretty bad at representing information and so, he hired Mr. Murphy as his Excel expert who inevitably messed up the names of the companies and wrote a ton of gibberish. The values were correct but the names weren’t. The following was the output:
He knew the companies’ performance at the back of hand though and so, made certain observations. However, he was not great at calculations and so, he has hired you, Mr. WIMWI to help him crack the code! Can you do it? For all questions, assume that WB purchased shares only in multiples of 10.
1. If the two IT companies showed the two largest absolute variations in the share prices and the two Automobile companies showed the two least absolute variations, what was the approximate growth Mr. WB would have seen from the shares of the two Banking companies? (answer should be accurate up to two digits after the decimal point)
2. If Mr. WB had purchased a total of 60 shares of exactly 4 of the 6 companies, then the maximum possible percentage return on investment as on 26 September 2017 based on the shares of these 4 companies only could be (answer should be accurate up to two digits after the decimal point)
3. If one of the two IT companies showed the highest percentage variation in the share price while the other IT company showed the lowest percentage variation, then what was the combined percentage change in the share prices of the two IT companies? (answer should be accurate up to two digits after the decimal point)
4. If Mr. WB had purchased a total of 40 shares of exactly 4 of the 6 companies, what could be the minimum possible percentage return that he would have got? (answer should be accurate up to two digits after the decimal point)
