The sum of 5 consecutive even numbers A,B,C,D and E is 130. What is the product of A and E ?

A) 720
B) 616
C) 660
D) 672

Correct Answer:



C) 660

Description for Correct answer:
Let five consecutive even number be

A=x,B=x+2,C=x+4,

D=x+6 and E=x+8

According to the question,

x+x+2+x+4+x+6+x+8=130

=> 5x + 20 = 130

=> 5x = 130-20=110

x = \( \Large \frac{110}{5} \) = 22

A = 22

E = x+8=22+8=30

\( \Large A\times E \)= \( \Large 22\times 30 \)=660
