Explanatory Answer
Method of solving this CAT DILR Question from Analytical Reasoning question
(b) a, b, c, d and e represent numbers 2, 4, 5 , 6 and 10
From (I), a + c = e
From (II), b 2d b 10 = or d = 5 accepted
From (III), a + e = b
From above we have,
a + a + c = b => 2a + c = 10, a = 4 => e = 2, c = 6
Hence, a = 4; b = 10; c = 2; d = 5; e = 6 is the required solution.
