Quantitative Aptitude And Mathematics

  1. 1. STATISTICS & BUSINESS PROBLEMS AFTERSCHO☺OL – DEVELOPING CHANGE MAKERS CENTRE FOR SOCIAL ENTREPRENEURSHIP PGPSE PROGRAMME – World’ Most Comprehensive programme in social entrepreneurship & spiritual entrepreneurship OPEN FOR ALL FREE FOR ALL
  2. 2. STATISTICS & BUSINESS PROBLEMS Dr. T.K. Jain. AFTERSCHO☺OL Centre for social entrepreneurship Bikaner M: 9414430763 [email_address] www.afterschool.tk , www.afterschoool.tk
  3. 3. Find the binomial distribution if the mean is 48 standard deviation is 4.
  4. 4. P(A) =1/3, P(B) = ½, P(A-B) = 1/5, what is the probability that only B will happen? <ul><li>P(A) = 1/3 (WHICH INCLUDES A+B ALSO). </li></ul><ul><li>P(A-B) = 1/5 (ONLY A – BECAUSE HERE B IS EXCLUDED) </li></ul><ul><li>P(A &B) (Together) = 1/3-1/5 = 2/15 </li></ul><ul><li>P(ONLY B) = ½ - 2/15 = 11/30 ans. </li></ul>
  5. 5. What is the probability that 4 children selected at random would have different birthdays? <ul><li>For the first boy there are 365 choices, for second, there are 364 choices, for third there are 363 choices and for 4 th there are 362 choices. Thus the probability is </li></ul><ul><li>(365*364*363*362) / (365^4) = .983644 answer </li></ul>
  6. 6. There are 3 boxes with following details: Box 1. (5 red,7 white, 6 blue) box 2: (4red,8 white,6 blue), box III : (3 red,4 white,2 blue), if one ball is drawn at random from each of these, what is the probability that we have 3 balls of same colour?
  7. 7. Solution. <ul><li>Let us assume that we get Red from each: </li></ul><ul><li>5/18*4/18* 3/9 = 60/2916 </li></ul><ul><li>For white : </li></ul><ul><li>7/18*8/18*4/9 = 224 /2916 </li></ul><ul><li>For blue: </li></ul><ul><li>6/18*6/18*2/9 = 72/2916 </li></ul><ul><li>= 356/2916 : = .122 ans. </li></ul>
  8. 8. What is the probability that a leap year selected at random will have 53 Saturdays? <ul><li>We have 52 week plus one extra day in a normal year. This extra day can be any one from Mon. to Sun. In leap year, we have 2 extra days thus we can have these 2 extra days on any of MON+Tue or any combination of 2 days. </li></ul><ul><li>Thus we have 2/7 probability that the leap year will have 53 Saturday. Ans. </li></ul>
  9. 9. A pocket of 10 components include 3 defectives. If 4 components are selected from the pocket at random, what is the expected value of the number of defectives? 1.199 .099 .6 .5 0 .033 .3 .5 .167 7c1*3c3/10c4 7c2*3c2/10c4 7c3*3c1/10c4 7c4/10c4 3 2 1 0
  10. 10. 30% failed in Acct. 40% failed in Eco and 50% failed in at least one of these papers. If we randomly pick up a person, who is failed in Eco,what is the probability that he has passed Acct? <ul><li>Let us find the % for those who have failed in both the papers. </li></ul><ul><li>30+40 – X = 50 </li></ul><ul><li>X = 20 thus there is 50% probability that he has passed Accts. </li></ul>
  11. 11. A problem was given to Mayank, Goti and Nidhi (pgpse students), the probability they will solve is 1/3, 1/5 and ½, what is the probability that the problem will be solved? <ul><li>Let us assume that Mayank doesn’t solve it: 2/3, Goti doesn’t solve it 4/5 and Nidhi also doesn’t solve it ½. All 3 don’t solve it : </li></ul><ul><li>2/3*4/5*1/2 = 8/30. thus problem will be solved : 22/30 or 11/15 answer. </li></ul>
  12. 12. If NC2 = NC5, what is N ? <ul><li>N = 2+5 = 7 </li></ul><ul><li>Thus N = 7 ans. </li></ul>
  13. 13. How many numbers of 5 digits can be formed with 0,1,2,3,4,6,8? <ul><li>For the first digit we have 6 options, for 2 nd digit we have 6 options (the digit used earlier will not be used), for 3 rd digit we have 5 options, and for 4 th digit we have 4 options and for last 5 th digit we have 3 options). Multiply all these to get the answer: </li></ul><ul><li>=6*6*5*4*3* </li></ul><ul><li>=2160 answer. </li></ul><ul><li>If repetition is allowed: </li></ul><ul><li>6*7*7*7*7 </li></ul><ul><li>=14406 ans. </li></ul>
  14. 14. There are 2 boxes. The first contains 3 red and 5 white balls. The 2 nd contains 4 red and 6 white ball. One ball is taken from first box and transferred to 2 nd box. And then another ball is drawn from the second box. What is the probability that the second ball is Red? <ul><li>Let us assume that we draw red ball from first box and then we have 5 red in 2 nd box </li></ul>
  15. 15. Solution …. <ul><li>3/8 *5/11 = 15/88 </li></ul><ul><li>Suppose we draw white ball from first box: </li></ul><ul><li>5/8*4/11 = 20/88 (multiply because there is & between them). </li></ul><ul><li>Now add these two: </li></ul><ul><li>35/88 answer. (add because there is OR between them). </li></ul><ul><li>(in first possibility, we have red ball from the first box and again red ball from 2 nd box. In 2 nd possibility, we have white from 1 st and red from 2 nd box.). </li></ul>
