A survey was conducted in a community of 350 people regarding three
games - Chess ,Carrom and Chinese Checkers. The Following information is
obtained in the survey.
(i) Thrice the no. of people who play all the three games is equal to the no. of people who Chinese Checkers .
(ii) The no. of people who play Chinese Checkers and Carrom is equal to the no. of people who play Chess only
(iii) In every three people who play Chess and Chinese Checkers only, there are five people who play none of the three games.
(iv) In every seven people who play Chinese Checkers, four people play Carrom also.
(v) For every four people who play exactly two games,there is one person who plays Carrom and Chinese Checkers only and two persons who play none of the three games
Questions:
1. How many people play exactly two games?
2. How many people play Chess but not Carrom?
3. How many people do not play Chinese Checkers?
4.How many people play Chess or Carrom
The relationship between the price of gasoline y (in Rupees) and its weekly supply, x (in gallons) is y = 0.37+ 0.45/x . If the weekly supply decreases at a rate of 50 gallons per week when the supply is 600 gallons, the price of gasoline will be changing at the rate of:
a) Rs 0.625x10^-4 b) Rs 0.625x10^-3 c) Rs 0.625x10^-2 d) Rs 0.625x10^-1
I have a query on Euler's Theorem.
For e.g. Remainder of 3^15 divided by 12. So essentially, we find the Euler's of 12, which is equal to 4. And then convert 3^15, in its terms. Which is 4k+3. And then it reduces to 3^3 divided by 12, Remainder = 3. All perfect.
My doubt is, according to this, 3^4k divided by 12, should give remainder 1. But when i put in k = 1, 81 divided by 12, remainder is not 1, but 9.
What am I missing?
