Let the First odd number be 'x'

Then, 8 consecutive odd numbers are as

x-8, x-6, x-4, x-2, x

x+2, x+4, x+6

Now, (x-8)+(x-6)+(x-4)+(x-2)+x+(x+2)+(x+4)+(x+6)=656

⇒ 8x-8=656

⇒ 8x=656+8

⇒ 8x=664

⇒ x=83

Now, let four consecutive even numbers be y-2, y, y+2 and y+4

Now, 4y+4=87×4

⇒ 4y+4=348

⇒ 4y=348

⇒ y=86

Now, smallest even number =86-8= 78

Second largest even number =88

∴ Sum of both the numbers =88+78=166

Hence, Option E is correct.
