RATIO AND PROPORTION

Questions


1. The Vanar Sena took with them food for 12 days. On the 4th day of the journey, they realized that 20% of the food left was spoiled due to high heat. If each Vanar ate 400 grams of food each day, what should be their new food ration per day per vanar to survive the 12 days?


2. If they got tired on the way due to reduced food intake for 4 days, and calculated that they still had 8 more days to travel, by how much should they increase or decrease their food intake?


3. 2 days away from the seas shore, they would smell the salty ocean winds and got energized again and started marching ahead very fast. If they plan to complete the remaining trip in 1 day, and want to consume 400 grams off food a day, how much food will remain as excess or fall short by the time they reach the shore?


4. If the Vanar Sena had 5000 more foot-warriors, they would have had to carry 5% more food than they did. What was the strength of the Vanara Sena?

Warren Bufffett

Questions

  

1) What portion of his lifetime did Warren take to make his first billion-dollar fortune?

2) If Howard Buffet had to invest in a 10-year Railway bond for Warren in 1942, which one should he choose:

         a. A 10% Simple Interest coupon bond paid in equal parts semi-annually

         b. A 4% compound interest coupon paid annually

3) Assuming that the shares of Cities Service Preferred today have increased in value by 3800%, what is the average annual ROI on the shares for Warren? 

4) Assuming Warren invested all his savings in the shares of Cities Service Preferred, and then took up a part-time job of delivering newspapers before school hours; then what percentage of his earnings did he save every month when he bought a stake at the Omaha farm exactly three years later. Assume that he invested 40% of his total savings in the farm stake purchase?

5) The estimated value of the Omaha farm today is twelve-hundred times the value of the shares of Cities Service Preferred. So which investment of the two has been better for Warren in terms of ROI. (Take relevant data from Q#2?

6) Assuming the ROI on X-Box is 25% greater than the ROI for pinball, all other things remaining constant how much would a merchant making an investment of $20 make on X-Box?

7) On any working weekday, the Pinball would make $10 for the barbershop, and $15 daily on weekends. The Pinball was under maintenance on every 8th weekend and did not generate any revenue for the shop during that time. If the proportion of total revenue generated during weekdays to the total generated on weekends during the year was 5:3, then for how many days in total did the barber shop stay closed during that year considering the fact that the owner never closed the shop on those days where the trend suggested the probability of making more money was greater?

8) If each of the Pinball machine cost 20% more than the one bought earlier, and sold for 25% more than the previous sale, then what was the ratio of ROI for each of the Pinball machines?

Warren Buffett Early Life

Buffett was born in 1930 in Omaha, Nebraska to mother Leila Stahl Buffett and father Howard Buffett, who worked in investing himself before winning a congressional seat in 1942.


Buffett, growing up with an investor father, took a shine to that world even as a young child. He decided to purchase his first stock at just 11 years of age -- three shares of Cities Service Preferred at $38 a share. When he moved to Washington D.C. as a teenager after his father was elected into office, he began delivering copies of The Washington Post and made $175 per month.


In addition, at 14 years of age, he used $1,200 in savings to purchase a stake in a 40-acre farm just outside of Omaha. An interest in investing and business was instilled into young Warren Buffett at a young age, before he even entered high school.

By the time he was finishing high school, Buffett already fashioned himself a businessman. He and his friend purchased a pinball machine for $25, and placed it in a barbershop. In no time at all, they had three different machines in three different locations, eventually selling this "business" for $1,200. That was the precursor to his journey of becoming a billionaire in 1985.
