A can do 1 by 2 of a piece of work in 5 days. B can do 3 by 5 of the same work in 9 days and C can do 2 by 3 of that work in 8 days. In how many days can three of them, together do the work?(1) 3 days (2) 5 days (3) 9 by 2 days (4) 4 days |
|
Answer» Answer: ATQ,A can do 1/2 of the WORK in 5 days => A can do the WHOLE work in 5 × 2/1 = 10 days B can do 3/5 of the work in 9 days => B can do the whole work in 9 × 5/3 = 12 days C can do 2/3 of that work in 8 days => C can do the whole work in 8 × 3/2 days = 12 days. Therefore, ( A + B + C)’s 1 days’ work = 1/10 + 1/15 + 1/12 Hence, A + B + C can COMPLETE the whole work in 4 days |

Please anyone here to help me . Don't copy from Google as it is not having answer.find value of x in 1/x+4 - 1/x-7 = 30please please find answer |
|
Answer» 1 Or 2 roots of given Quadratic equation. Explanation: Given \frac{1}{x+4}-\frac{1}{x-7}=\frac{11}{30} x+4 1
− x−7 1
= 30 11
\IMPLIES \frac{[x-7-(x+4)]}{(x+4)(x-7)}=\frac{11}{30}⟹ (x+4)(x−7) [x−7−(x+4)]
= 30 11
\implies\frac{x-7-x-4}{x^{2}-7x+4x-28}=\frac{11}{30}⟹ x 2 −7x+4x−28 x−7−x−4
= 30 11
\implies\frac{-11}{x^{2}-3x-28}=\frac{11}{30}⟹ x 2 −3x−28 −11
= 30 11
Do the CROSS multiplication, we GET => 30 = 11(x²-3x-28)/(-11) => 30 = -(x²-3x-28) => x²-3x-28+30 =0 => x²-3x+2=0 Splitting the middle term, we get => x²-1x-2x+2 =0 => x(x-1)-2(x-1)=0 => (x-1)(x-2)=0 =>x-1 = 0 or x-2 = 0 => x = 1 or x = 2 Therefore, Roots of the given quadratic equation are 1 , 2 ••• MARK ME AS BRAINIEST ..

A businessman instituted an annual awardin a city school, with a part of the awardgiven to the school itself to improve itsfacilities. It was stated that if a student froma wealthy family were to top the annualexamination, the school would receivetwice the amount awarded to the student.On the other hand, if a student from a poorfamily were to top the annual examination,the student would be awarded twice theamount that the school would receive. Inone year, two students, one rich and onepoor, jointly topped the annual examination.What fraction of the award money did theschool receive in this case? |
|
Answer» Answer: The poor student gets (1/3) of the prize money. The rich student gets (1/6) of the prize money. Step-by-step explanation: LET N be the amount of the prize money. With RESPECT to the rich student, the prize money gets divided into a 1:2 ratio. So the rich student gets 1/3 of N/2 = (1/6)N and the SCHOOL gets (2/3) of N/2 = (1/3)N The OPPOSITE is true for the poor student. So the prize money is divided as follows:
(1/6)N goes to the rich student (1/3)N+(1/6)N = (3/6)N = (1/2)N goes to the school (1/3)N goes to the poor student
So the school gets half of the price money. The poor student gets (1/3) of the prize money. The rich student gets (1/6) of the prize money. Hope it HELPS!! |

Q => A die is thrown twice. What is the probability that(i) 5 will not come up either time? (ii) 5 will come up at least once? |
|
Answer» A dice is THROWN twice. What is the probability that (i) 5 will not come up either time ? (II) 5 will come up at LEAST once ? Probability of getting 5 on throwing the dice once . Sample space For tossing it twice we have 11 outcomes Number of outcomes we get on throwing a dice once = 18 So , hence total outcomes on throwing it twice = 18 × 2 = 36 Number of times we can get a 5 = 11 i ) Number of times we won't get a 5 Event 1 = Probability of not getting a 5 either time Event 1 = Event 1 = _____________________________________ ii ) Number of times we will get 5 atleast once = 11 Event 2 = Probability of getting a 5 atleast one time Event 2 = Event 2 = _______________________________________ |
