Q. What is the remainder when a five-digit number PQRSR is divided by 125?(P, Q, S and R are distinct digits.)A: A = (PQSR)/4 and A when divided by 25 leaves a remainder 13.B: R^S = S^R and when a two digit number QR is divided by 10, the remainder is greater than 3.Mark (a) if the question cannot be answered even by using both statements together.Mark (b) if the question can be answered by using both the statements together, but cannot be answered by using either statement alone.Mark (c) if the question can be answered by using either statement alone.Mark (d) if the question can be answered by one of the statements alone, but cannot be answered by using the other statement alone.
C?

lol..koi ni bhai..

waise boss saamne baitha hua tha, upar se ans nahi nikal raha tha.. chup chupke qns solve karne ki koshish kar raha tha aise situation mein..

@bullseyes said:
It is given that the quadratic equation X^2 €“ PX + Q = 0 has distinct and real roots, where P and Q are distinct integers. What is the value of (2*P + 3*Q)?A: Roots of the given equation are consecutive positive integers and (P, Q B: Roots of the given equation are consecutive non-zero integers and (P, Q Mark (a) if the question cannot be answered even by using both statements together.Mark (b) if the question can be answered by using both the statements together, but cannot be answered by using either statement alone.Mark (c) if the question can be answered by using either statement alone.Mark (d) if the question can be answered by one of the statements alone, but cannot be answered by using the other statement alone.
Is it option (a)?
Since the roots are real and distinct, b^2-4*a*c > 0
Here, p^2 - 4q > 0

From condition a, p and q can be 3,2...4,3...5,4
From condition b, p and q can even assume negative values so there is no way to determine the solutions to the equation

Please correct me if i am wrong
At the end of year 2068, Shepard bought nine dozen goats. Henceforth, every year he added p% of the goats at the beginning of the year and sold q% of the goats at the end of the year where p>0 and q>0. If Shepard had nine dozen goats at the end of year 2072, after making the sales for that year, which of the following is true?

[1] p = q
[2] p
[3] p > q
[4] p = q/2

is ques ko karne ka koi sahi sa method batao...smthng sort of verbal n logical..n also had there been an option q=p/2..tab kya karte??

option 2
@sauravd2001 said:
@nick_baba bhai p>q?
yep frnz..ans is p>q ..but agar option q=p/2 bhi hota to ??
