Question: How many children are there between P and Q in a row of children ?

Statements:

  1. P is fifteenth from the left in the row.
  2. Q is exactly in the middle and there are ten children towards his right.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Both I and II are sufficient
Answer: Option
Explanation:

From II, Q being in the middle, there are 10 children to his right as well as to his left. So, Q is 11th from the left. From I, P is 15th from the left.

Thus, from both I and II, we conclude that there are 3 children between P and Q.

Rameez.

Yes, you are correct.

Kaunain said:   3 years ago
3 children is the correct one because Q is 11th so 12 13 14 are between 15th P.

Supraja said:   3 years ago
Why q is having the position only at 11 there is nothing mentioned that q position is at only 11 can anyone explain it?

Rameez said:   6 years ago
P is (15) from left in a row .... P_ _ _ _ _ _ _ _ _ _ _ _ _ 1 -->( i )

Q is in the exact middle means it has equal no on either sides of it, right? so if 10 are on its right then 10 will be on its left too. Hence, moving from left to right;

Q _ _ _ _ _ _ _ _ _ _ it means that Q is at 11th position and from 1st statement, we know P is at 15th position, so.... situation will be like where p is 15th and Q is 11th.

P _ _ _ Q _ _ _ _ _ _ _ _ _ _.

we need 1 and 2 both statements to conclude that there are 3 children in between.

Aakash said:   7 years ago
I agree @Rohit.

There will be 4 children b/w them.

Manish said:   7 years ago
15 14 13 12 11 in this way there are 3 children in between 15 and 11.

Rohit said:   7 years ago
15 - 11 = 4 children should be there in b/w them.

From the 1st statement, P is at 15th position from left in row.

Q is exactly in the middle of the row and there are 10 childrens towards his right so Q is at 11th position.

From both statements we can find the difference between P and Q which is equal to 3.
