To determine which is greater between 50% of 40 and 40% of 50, we can calculate the actual values.
50% of 40 is 0.50 x 40 = 20.
40% of 50 is 0.40 x 50 = 20.
Therefore, both values are equal at 20.

40/50 reduces to 4/5 which would be 80 percent thus making it a B

6 litres of 50% + 4 litres of 25%
The question is slightly ambiguous, so I'll list the two possibilities:If the original price is 50, and the new price is 50 + a 40% markup, then we can calculate as follows:New price = 50 + 40%= 50 x 1.4= 70If however you meant that the original price is 50 including a 40% markup (eg tax), and you want to calculate the new price with this markup removed, we calculate the answer as:New price +40% = 50New price x 1.4 = 50New price = 50 / 1.4= 34.84= 35 (approx)
Geometric mean of 32 and 50 = sqrt(32*50) = sqrt(1600) = 40
