Chess Champion: In a chess tournament, intermediate players can sometimes beat more advanced players. Because they are not aware of more advanced moves, the intermediate players will make simpler strategic choices, which in turn confuse advanced players who are used to playing with other advanced pl...

The Copper Butterfly, an unsigned classical painting, was carbon dated to ascertain its age, previously estimated at 520 years. Manuscripts from that time reveal that one of two possible artists must be responsible for the painting's creation. One of the artists died one week after the painting had...

The sum of consecutive integers can be found by the formula = > Average * number of terms. Here since number of terms is 100 , we get Sum = (Average * 100). We would like to find if this sum is divisible by 100 , so sum/100 => (Average * 100)/100. The 100 in the numerator and denominator cancel out,...

Ok, the sum is not an integer . But the 100 in the numerator gets cancelled with the 100 in the denominator. Sum = (Average * 100)/100. Hence sum = Average. If the value can get cancelled out, it means that sum is divisible by 100 rite? It might sound silly, but I am confused.

Consecutive integers
Is the sum of the integers from 54 to 153, inclusive, divisible by l00? Sum=Average * number of terms Sum = Average * 100 ( There are 100 numbers between 53 and 154 ) inclusive . Hence sum is divisible by 100. Is that not true ? But Manhattan says since there are even number of items, the sum can ne...

@GMATGuruNY :
I was able to understand alligation, but my point was to see if my method can actually work.
And you have also added another mixture question to help me relate. Wow, thanks

The total spirit in the 35 litres is 28 litres and water is 7 litres.
8x of spirit from vessel 1 and 5x of spirit in vessel 2 makes up 28 litres. Hence from spirit from vessel 1 is (8x/13x)*28. Similarly (3x/4x)*7

mixture
Two vessels contain mixtures of spirit and water. In the first vessel the ratio of spirit to water is 8 : 3 and in the second vessel the ratio is 5 : 1. A 35–litre cask is filled from these vessels so as to contain a mixture of spirit and water in the ratio of 4 : 1. How many litres are taken from...

Apples
Hi, Let the no of bushels harvested yest be by and today be bt. When both combined, the eqns are the following. Let T be the total bushels harvested - y(42) + (by-42)(1.5y)=180 y(42) + (by+10-42)(1.5y) = 240 Solving both , I get y= - 4. With a negative value, the value of by cannot be calculated. He...

Hi Brent@GmatprepNow, I am a little doubful abt one of the statements Now we can combine these inequalities to get: y-2 < x < 2y-6 Next, remove the x to get: y-2 < 2y-6 If at all we are going to remove soemthing from an inequality, we are supposed to do so to other parts also rite? y-2 < x < 2y-6 y-...

Hi Anju@Gurome,
Since the qn says all the points lie on a circle, the measure of line segment RU is pretty much the same as finding x/360*2*pi*r. i understand that this repeats whats already given, but whats the difference here.?
Also can u illustrate with the help of a diagram pls?

@GMATGuruNY : Hi why are we considering one of the end poles to be 2400 and not 2600 ?
2600---2820------3000 ( Why is this not the correct number line) ?
