The average monthly income of P and Q is Rs. 5050. The average monthly income of Q and R is Rs. 6250 and the average monthly income of P and R is Rs. 5200. The monthly income of P is:
A.
3500
B.
4000
C.
4050
D.
5000
Answer: Option B
Explanation:
Let P, Q and R represent their respective monthly incomes. Then, we have:
P + Q = (5050 x 2) = 10100 .... (i)
Q + R = (6250 x 2) = 12500 .... (ii)
P + R = (5200 x 2) = 10400 .... (iii)
Adding (i), (ii) and (iii), we get: 2(P + Q + R) = 33000 or P + Q + R = 16500 .... (iv)

What is the number?
I.
The sum of the two digits is 8. The ratio of the two digits is 1 : 3.
II.
The product of the two digit of a number is 12. The quotient of two digits is 3.
A.
I alone sufficient while II alone not sufficient to answer
B.
II alone sufficient while I alone not sufficient to answer
C.
Either I or II alone sufficient to answer
D.
Both I and II are not sufficient to answer
E.
Both I and II are necessary to answer
Answer: Option C
Explanation:
Let the tens and units digit be x and y respectively. Then,
I. x + y = 8 and
x
=
1
y
3
I gives, 4y = 24 y = 6.
So, x + 6 = 8 x = 2.
II. xy = 12 and
x
=
3
y
1
II gives, x2 = 36 x = 6.
So, 3y = 6 y = 2.
Therefore, Either I or II alone sufficient to answer.
