Let a, b, c, d, e, f, g be consecutive even numbers and j, k, l, m, n be consecutive odd numbers. What is the average of all the numbers?1). 3(a + n)/22). (5l + 7d)/43). (a + b + m + n)/44). None of the above

Answer»

Since a, b, c, d, e, f, g be consecutive even numbers;

Suppose a = 2, b = 4, c = 6, d = 8, e = 10, f = 12 and g = 14.

Since j, K, l, m, n be consecutive odd numbers;

Suppose j = 1, k = 3, l = 5, m = 7 and n = 9.

∴ Average of all the numbers = (a + b + c + d + e + f + g + j + k + l + m + n)/12

Putting the values of every term as SUPPOSED above;

∴ Average of all the numbers = (56 + 25)/12 = 81/12 = 27/4

On checking with the options, any OPTION will not be satisfied with this data.

NONE of the above
