Question

Four numbers P, Q, R and S are such that P mean is 8, their mode is 10 and their range is 7. Find the value of P, Q, R
and S.

Answer 1

P, Q, R and S represent 5, 6, 7 and 8, but not in that order. If P × Q = RS, find the values of P, Q, R and S respectively.

(a) 7, 8, 5, 6

(b) 8, 7, 5, 6

(c) 7, 5, 8, 6

(d) Both A and B

SolutionP, Q, R and S represent 5, 6, 7 and 8, but not in that order. Also P Ã Q = RS. Letâs see the numbers in which option fit the above equation. (a) 7, 8, 5, 6 P Ã Q = RS 7 x 8 = 56 56 = 56 So, this is correct.(b) 8, 7, 5, 6P X Q = RS 8 x 7 = 5 x 6 56 = 56 So, this is correct.(c) 7, 5, 8, 6P X Q = RS 7 X 5 = 86 35 = 86 So, this is not correct. (d) Both A and B Yes, both A and B are correct. That means Option D is the right answer
