a, b, c and d are four consecutive numbers. If the sum of a and dis 107, what is the product of b and c?  Choose the correct choice from the following:	A) 2862	B) 2578	C) 2534	D) 3354	E) 4234
2862   2862   Here d = a + 3   a + a + 3 = 107   2a = 104   a = 52   So, numbers are 52, 53, 54 and 55   ∴ b × c= 53 × 54 = 2862
