I believe no sane maintenance department would dispatch and no sane flight crew would accept an A/C with such a discrepancy. To me the figure mentionned must be a typo.
Looking at the T/O and CLB reports, you can read the LH and RH fuel flows (WF) in lbs per hr. Converted to kg/hr the difference is 197 and 92 for T/O and CLB respectively.
