Number of chocolates with Daniel is X and the number of chocolates wit

Question

Number of chocolates with Daniel is X and the number of chocolates with Maria is Y. If X and Y are distinct, what is the number of chocolates with the one having lesser chocolates, out of Daniel and Maria?

(1) Sum of X and Y is greater than the positive difference between X and Y by 20.

(2) Maria has more chocolates than Daniel.

Hatakekakashi · Answer

X and Y are distinct

Using 1

X+Y - X-Y = 5

but here x>y or y< x

we need this relation

insufficient

using 2

y>x

combining

x+y - ( y -x ) = 5

we can find y and x

(C) imo

Hi

Sorry there was a flaw in the question. I changed the value from 5 to 20 now.

Can we have a solution for this please?

Hey  shiying  ,

Here you go:

Question is asking if X < Y, what is X? and if Y < X, what is Y?

So, basically we need to determine the value of the lowest.

Let's look options now.

1. Let's consider X < Y

X + Y = Y - X + 20

=> X = 10.

Now consider Y < X

X + Y = X - Y + 20

Y = 10.

Hence, For both the scenarios, I got the lowest value = 10. Hence, sufficient.

Now, Consider Statement 2:

It says X < Y. But we don't know anything about the values.

Hence, insufficient.

Therefore the answer is A.

"what is the number of chocolates with the one having lesser chocolates, out of Daniel and Maria?". I actually thought we were suppose to find the sum of the chocolates held by Daniel and Maria. Silly me. Thanks for the reply!

Hi , Isn't it mentioned that X and Y are distinct? Then how can we conclude that both are 10 ?

please help

abhimahna · Answer

Hi  rocko911  ,

I never mentioned both are 10. I said when X < Y , I am getting X = 10 and when I am taking Y < X , I am getting Y = 10

This means whichever is the lowest, the value will be 10.

Does that make sense?

mphil124 · Answer

You're going to have to explain this a little more. I don't see how we can conclude the lowest to be 10

Hello 
 
Statement 1 
Lets assume X < Y. Now we are given that  sum of chocolates  is greater than  difference between the chocolates  by 10. Here sum of chocolates = X+Y or = Y+X and difference between the chocolates = Y-X. So we are given that:
(Y+X) - (Y-X) = 10. When you solve it, you get 2X = 20 or X=10. So the one having lesser chocolates has '10' chocolates.

Now lets assume Y < X. Again,  sum of chocolates  is greater than  difference between the chocolates  by 10. Sum = X+Y or Y+X and difference between them= X-Y. So: (X+Y) - (X-Y) = 20. Solving it, we get 2Y = 20 or Y=10. Again the one having lesser chocolates has '10' chocolates.

We are not asked the value of either X or Y. We are asked the lesser value between X and Y. In either case, the one with lesser chocolates has '10' chocolates. So the lesser value between X and Y is '10' in any case.

hellosanthosh2k2 · Answer

Statement 1:
X + Y = 20 + |X-Y|
Let X > Y => Y is smaller
X + Y = 20 + X - Y => Y = 10
Let X < Y => X is smaller
X + Y = 20 - X + Y (as |x| = -x , if x < 0)
X = 10

in either case, smallest is 10 (which is what the question asks) sufficient

Statement 2: clearly insuff

(A)

srinjoy1990 · Answer

I really liked statement A.

According to statement A, X+Y - |X-Y| = 20. This actually means, the sum of the 2 numbers is equal to 20 if they were equal, so one number is 10 and other is 30. Really nice.
