It is the sum of the two digits(9 + 8) in opposite quadrant.

The Puzzle has multiple interpretations . Read carefully and answer. Red is a colour and a word.

If the scales had been false on account of the pans being unequally weighted, then the true weight of the pudding would be 154 oz., and it would have weighed 130 oz. in one pan and 178 oz. the other. Half the sum of the apparent weights (the arithmetic mean) equals 154. But the illustration showed that the pans weighed evenly and that the error was in the unequal lengths of the arms of the balance. Therefore, the apparent weights were 121 oz. and 169 oz., and the real weight 143 oz. Multiply the apparent weights together and we get the square of 143-the geometric mean. The lengths of the arms were in the ratio  II to 13. 154 and 143 is the true weight

If I walk 26 steps I require 30 seconds, and if I walk 34 steps I require only  18 seconds. Multiply 30 by 34 and 26 by 18 and we get 1,020 and 468,
the difference between which is 552. Divide this by the difference between 30  and 18 (that is, by 12) and the answer is 46, the number of steps in the stair­ way, which descends at the rate of 1 step in 1 ~ seconds. The speed at which I walk on the stairs does not affect the question, as the step from which I alight will reach the bottom at a given moment, whatever I do in the mean­ time.

The times were 8 hours 23+71/143 minutes, and 4 hours 41 +137/143  minutes. We  are always allowed to assume that these fractional times can be indicated in clock puzzles.

The hour indicated would be exactly 23+1/13 minutes after four o clock. But because the minute hand moved in the opposite direction, the real time would be 36 +12/13 minutes after four. You must deduct the number of minutes indicated from 60 to get the real time.
