9 + 5 + 4 = 18 ÷ 9 + 16 = 18 = 18
After changing '+' = ÷ , '-' = x
'x' = '+' '÷' = -
the equation, 46 - 6 + 4 x 5 ÷ 3 = 71
CHS = 46 x 6 ÷ 4 + 5 - 3
= 276 ÷ 4 + 5 - 3
= 69 + 5 - 3
= 74 - 3 = 71 R.H.S.
After changing '+' and '-' , 8 and 7 the appropriate equation is,
6 + 8 x 2 - 7 = 0
L.H.S. = 6 - 7 x 2 + 8
6 - 14 + 8
14 - 14 = 0 = R.H.S.
25 ÷ 3 x 7 - 8 + 12 = 19.3
N = P ? F ? L = K
Hence F ? K. Which means either
I (F = K) or II (F > K) follows
Z > T < M < J
Which means T < J. Hence I follows.
But Z and J can't be compared. Hence II does not follow.
C ? G ? Q = Z ? R
Hence G ? Z and I follows.
Also C ? R and II follows.
L > K > M ? N > O
Hence O < M and I follows.
Also O < K and II follows.
If only conclusion II follows
