The sum of the present ages of a father and his son is 99 years. When the father was old as his son is now, his agewas four times age of the son at that time. The ratio of the present ages of the son and and the father is:(a) 3:7(b) 3 : 8(c) 4:9(d) 4:7 |
|
Answer» f+s=99so s=99-fnow suppose x years ago f-x=99-f so 2f=99+x so f=(99+x)/2so f-x=4(s-x)(99+x)/2=4s-4x99+x=8s-8x99=8(99-f)-9x=99(8)-4(2f)-9x9x-4(99+x)=7(99)9x-4(99)-4x=7(99)so x=27so f=(99+27)/2=126/2=63so s=99-63=36so ration of son to father = 36/63=4:7 |

(a) A bag contains 4 red, 3 blue and 2 whiteballs. If three balls are drawn one by one(without replacement), what is the probabilitythat all three balls are red?(b) Two dice are thrown simultaneously. Whatis the probability of obtaining a total scoreof 7? |
|
Answer» Ans :- On a two unbiased dice, there are36(6×6) possible outcomes. In order to get a sum equal to 7, the outcome from the two unbiased dice should be either of the following:{1,6} {2,5} {3,4} {4,3} {5,2} {6,1} There are 6 possible outcomes that will result to a sum of 7. So: =6/36=1/6=0.167=0.167or16.67% The probability of getting a sum equal to 7 is16.67%. |
