Question
a, b, c, d and e are five consecutive even numbers. If
sum of a and d is 162, what will be the sum of all the 5 numbers?Solution
Series a, b, c, d, e are consecutive even nos. d = a + 6 Given a + d = 162 ⇒ a + a + 6 = 162 ⇒ 2a = 156 ⇒ a = `156/2` = 78 Sum of all the 5 nos. = 78 + 80 + 82 + 84 + 86 = 410.
