@somebody_33 Жыл бұрын
This is actually easy for a Math Olympiad question. Suppose x is one number. The next one would be x+1, and the next one x+2. Now, we can write the sum: x+(x+1)+(x+2)=60. We can simplify the equation to 3x+3=60. Subtracting 3 on both sides, we get 3x=57. We can divide 3 on both sides to get *x=19.* The largest number will be x+2, and if we substitute 19 for x, we get 19+2, which equals *21.* Therefore, *D is the final answer.*

See look at the options DO NOT use traditional methods using x to calculate the value rather if you see the options you can infer that if 21 is the largest other two are 19 and 20 if you add these together you will get 60 so 21 is the correct answer

this is very bad approach to solve these type of questions instead assume the first number be x and x+1,x+2 then x+(x+1)+(x+2)=60 3x+3=60 3x=57 x=19 hence the numbers are 19,20,21
@parikshitkulkarni355110 ай бұрын
Instead of saying its a bad method, you should say it's a more clever method if you see. Because 20+20+20 is 60 and if you subtract one from one 20 and add that to the other 20 you get 19+20+21 equals 60.

Let the three numbers be x-1, x , x+1. So, (x-1) + (x) + (x+1) = 60 3x = 60 x = 20 Hence, the largest number = x + 1 = 20+1 = 21.

Let the 2nd no be x so 1st is x-1 then 3rd no is x +1 so sum is x -1+ 1 + x+x = 3x = 60. SO x=20 and the largest no. Is x +1 that is 21.

That's not a solution. If X is the number you seek, then X+(X-1)+(X-2) = 60 = 3X -3. Then 3X = 63. So X = 21.

Why not 30? Because 60/2 = 30… 30 + 30 = 60 _but_ we need 3 numbers so if we subtract 1 from the first 30 we get: 1+29+30 = 60 Right!? Edit: Why not 1+2+57 = 60 And are we limited to integers? Am I stupid? Idk, I think the question needs to be re-stated because you can literally pick any number of the four options that were given. Edit2: okay, nvm, she meant the mathematical definition of consecutive.

No way this is an olympiad question, I don't believe it. a+b+c=60 60/3 since there are 3 numbers. They have to be dancing somewhere around 20. 1 less than it, 1 more than it. 19 ,20, 21. 21 is the largest number of the 3. As you can tell, I didn't really take an algebraic approach but you could also solve it that way. x+x+1+x+2=60 3x+3=60 3x=57 x=19, x+2 is the largest number 19+2=21

Let the first consecutive number be x So, the second consecutive number is x+1 the third consecutive number is x+2 Equation according to the question - x+x+1+x+2 = 60 3x+3 = 60 3x = 60-3 3x = 57 x = 57/3 x = 19 First consecutive number (x) = 19 Second consecutive number (x+1) = 19+1 = 20 Third consecutive number (x+2) = 19+2 = 21 So the three consecutive numbers whose sum is 60 are 19, 20 & 21. Answer check - 19+20+21 = 60 This is what we needed according to the question so the answer is correct By a 8th grader.... ❤
