There are equal number of odd and even numbers between 412 and 680

So if we can find the difference between 412 and 680 and divide it by 2, we get the number of even or odd numbers

We also have to add 1 to the result since the the above calculation doesn't include 412 as even number

Total number of buildings = \(\frac{680-412}{2} + 1\)

= \(\frac{268}{2} + 1\) = \(134 + 1 = 135\)

Hence option B

Ans: B

(680-412)/1 + 1 = 269

680 and 412 are both even numbers
=> number of even numbers is 1 more than number of odd numbers

269 = 135 + 134
=> 135

let x=number of buildings
412+2(x-1)=680
x=135
