C =66 Let the number of the birds flying be X X + 1/2 X + 1(the bird that said hello)= 100 X +1/2X +1 = 100 X+0.5X +1 =. 100 1.5X = 100 - 1 1.5X = 99 X = 99/1.5 X = 66 6 Likes |

it all depends what "we need half of us plus you" stands for? it could be answer A) 198.... half of 198 is 99+1 (you) equals 100 it could be answer C) 66... half of 66 is 33, 66+33 is 99 +1 (you) equals 100 it could be answer F) 199... half of 199+1 (200) equals 100 5 Likes |

C. 66 Let 'x' be the number of birds that met a bird. If half of 'x' plus 'x' plus a bird sums up to 100, then x + x/2 + 1 = 100 x + x/2 = 100 - 1 (2x + x) /2 = 100-1 3x/2= 99 3x = 99 * 2 3x = 198 x = 66 x/2 = 33 : 66 + 33 + 1 = 100 Modified ( Corrections made) 1 Like |

Nwodosis: Ol boy, if na you teach me maths for secondary school maybe I for no hate am pass Corona. You sabi book aswear. Your answer dey on point because even me work am for my head say... 66 birds dey fly Half of the 66 na 33 When you come add the 66 wey been dey fly join the half of 66, you go get 99. Now, come kpake the gbeborun bird wey dey say hello join the 99, Wetin you go get go be wanhundred (100) kpakam. Clap for me. Acada hard oh 5 Likes |

Half of 198 is 99. 99 + 1 is 100 198 it is |
Re: Let Me See How Critical People Can Think,let's See Who Can This Simple Equation by Nobody: 6:48pm On Apr 06, 2020 |
The equation you want is x + 1/2x+1 = 100 Solving will give you x = 66 Meaning half of 66 = 33 66 + 33 + 1 =100 |

AndroBlaze:wrong Compare the two statements below: "we need half of us plus you to make hundred". "we need half of us plus you to make us hundred." "Make us" show that they are part of the equation Hence x+x/2+1 = 100 x=66 1 Like |

Re: Let Me See How Critical People Can Think,let's See Who Can This Simple Equation by Xclusiveme: 9:32pm On Apr 06, 2020 |
The correct answer Is 198 |
Re: Let Me See How Critical People Can Think,let's See Who Can This Simple Equation by Xclusiveme: 9:35pm On Apr 06, 2020 |
We need half of us plus you to be hundred Let us be X And you be (1) 1/2 of X =X/2 X/2 + 1=100 X/2=100-1 X/2=99 MULTIPLICATION (CROSS MULTIPLY) X=99*2 X=198 |
Re: Let Me See How Critical People Can Think,let's See Who Can This Simple Equation by daewoorazer(m): 9:59pm On Apr 06, 2020 |
This is BODMAS in word problem 1/2 of (us + you)= 100 Since ‘you’ is 1 1/2 of (us + 1)= 100 Us + 1 = 200 Us = 199 Hence, the total of birds flying is 199 With the bird that greeted, they make a 200.... half of 200 is 100 Cc: lytech1 1 Like |

unless "half of us plus you" is explained clearly, there are too many possible RIGHT answers. thats like saying:"my room number is two zero two four"...is it 0024, 0044, 2044 or 2024?! 1 Like |

Let X = Birds. Then, X + X/2 + 1 = 100. equation (pcit). :. X + X/2 = 100-1 X + X/2 = 99, 2X + X = 99*2 3X = 99*2 X = 99*2 ÷ 3, X = 33*2, X = 66. Then substitute the value of X into equation X + X/2 + 1 = 100, Then, 66 + 66/2 + 1, 66 + 33 + 1, = 99 + 1, = 100. So the birds were 66 Also Please, people should take note of this *WE ARE NOT HUNDRED* we will need half of us (66) which is 33 plus you (1) Thank you |

MrBrownJay1: To be fair, the OP's problem was poorly worded on purpose and could never make any reputable exam, but I will still stick with the answer being A. 198. And as for your example above, again it is poor grammar and there can only be one answer which is 2024. For the others to hold successfully you would need to pluralize i.e. thats like saying:"my room number is two zero(s) two four(s)"...is it 0024, 0044, 2044 or 2024?! 1 Like |
