2b - (86 + 88) which value of b will be the closest to 0 for the question?
2b-(86+88) = 0
=> 2b-86(1+82) = 0
=> 2b-86(1+64) = 0
=> 2b-86*65 = 0
=> 2b-86*64 = 0 {according to the Q. ans will be close to 0, so we can use 64 in place of 65.}
=> 2b = 86*82
=> 2b = 88
=> 2b = (23)8
=> 2b = 224
=> b = 24
