I have to divide numbers from 1 to 9 into two team such that sum of numbers in one team is equal to the sum of various other group.Note : 6 cannot be flipped end to do it 9.

You are watching: How many circles do you see answer


1 2 3 4 5 6 and also 7 8 6Since summation of number 1-9(1 2 3 4 5 6 7 8 9) is 45 , therefore its impossible to divide right into two equal parts.Since we cant flip end 6 to make it 9 but we can flip 9 to do it 6 and also hence the solution

A competitive exam was hosted in which five students took part namely Billy, Gerry, Clark, Peeta and also Jonathan. In this exam, they had to answer 5 questions each out of which, three had multiple options as a, b or c and also two were straightforward true and also false questions. The five of them gave different answers to the questions and also the details space as provided below. Name 1 2 3 4 5Gerry c b True True FalseBilly c c True True TrueClark a c False True TruePeeta b a True True FalseJonathana b True False TrueNone of the two students gave the same number of correct answers. Can you find out the exactly answers come the question? Also, calculation the individual score of every the 5 guys.

It has actually been clearly stated that none that the 2 students gave same variety of correct answers i m sorry leads us to two various possibilities of exactly answers:Either (1 + 2 +3 + 4 + 5 = 15) or (0 + 1 + 2 + 3 + 4 = 10) was standing true.After evaluating the question, the maximum variety of correct answers possible with the answers Gerry, Billy, Clark, Peeta and also Jonathan gave:Question 1 = 2 (b or c)Question 2 = 2 (b or c)Question 3= 4 (True)Question 4 = 4 (True)Question 5 = 3 (True)Let us an initial assume with the maximum variety of correct answers possible according come our data which space 15 (2+2+4+4+3). Follow to it, Billy must have offered all exactly answers as he to be the just one that answered True for questions 3, 4 and also 5. However in the case, Gerry and Clark must have actually given specifically three correct answers. Furthermore, Peeta and also Jonathan need to have offered two exactly answers. As such none that them got all the five correct answers i m sorry is wrong according to what we have actually analyzed.Thus we move on come our next assumption according to which, the total variety of correct answers are 10 (0+1+2+3+4). Currently we must acknowledge that questions 3 and also Question 4 cannot be False as it will typical that the variety of correct answers would not it is in 10. Therefore the students providing wrong answers can not be Gerry, Billy and Peeta.Assume that Jonathan acquired all wrong, the will imply that Gerry, Clark and also Peeta every would have at least two exactly answers. Then, Billy would have to be the human being with just one exactly answer and in the situation, the correct answers for inquiries 1 and also 2 would certainly be a and also a respectively. Since that is not feasible as then the total number of correct answers would certainly be 1 (a) + 1 (a) + 1 (False) + 4 (True) + 2 (Flase) = 9.Thus it need to be Clark who has provided all not correct answers. The exactly answers are then b, a, True, False and False. Also, the scores are Clark (0), Billy (1), Gerry (2), Jonathan (3) and Peeta (4).
