A 1.08 B 1.10 C 1.14 D 1.16 E 1.18 The answer is D, its a GMAT plus question Quote Link to comment Share on other sites More sharing options...
sdasar Posted March 18, 2006 Share Posted March 18, 2006 If A,M,J are the dozens of eggs sold IN April, May and June, From the problem A = A; M = 3/2 A ; J = 2A The average for the three months is (A * 1.26 + A * (1.20)* 3/2 + A* 1.08 * 2 ) / ( A+ 3/2*A + 2A ) = A * 5.22 / A * 4.5 = 1.16 Quote Link to comment Share on other sites More sharing options...
