(A) f 1= 1 and f f2 = 2 is one of the possible solutions (B) f 1= I and f 2= 2 and it is unique<br />
(C) f1 = 2 and f2= 1 and it is unique (D) f1 = 2 and f2 = 1 is one of the possible solutions<br />
Solution 6. Putting all values of q, f and F in equation (1) and (2), two equations formed are<br />
identical.<br />
f 1+ 2f 2 = 5<br />
Thus, f 1= 1 and f 2 = 2 is one of the possible solutions.<br />
Hence, answer is (A)<br />
Directions: Questions 7 to 9 relate to the locations of WAREHOUSE AND<br />
SUPERMARKETS given below:<br />
A retail major has a warehouse (W) located at (16, 10) in a town having roads laid on a square<br />
grid parallel to the x and y axes. There are five retail supermarkets (M, N, 0, P and Q) located<br />
respectively at (4, 4), (6, 16), (16, 24), (20, 16) and (26, 4).<br />
Q.7 What is the ordering of the supermarkets from the nearest to the farthest from the<br />
warehouse?<br />
(A) P, M, N and Q, O (B) P, N and Q, 0, M<br />
(C) P, O, N and Q, M (D) P, O, M, N and Q<br />
Solution 7. According to given coordinates of warehouse and supermarkets the locations will be<br />
as follows. The distance of supermarkets from warehouse will be given by<br />
M = (16 - 4) + (10 - 4) = 12 + 6 = 18<br />
N = (16 - 6) + (16 - 10) = 10 + 6 = 16<br />
O = (16 - 16) + (24 - 10) = 0 + 14 = 14<br />
P = (20 - 16) + (16 - 10) = 4 + 6 = 10<br />
Q = (26 - 16) + (10 - 4) = 10 + 6 = 16<br />
So, the correct order from nearest to farthest from ware house will be: P, O, N and Q, M.<br />
Hence, the correct option is (C).<br />
