87 x 46 = 4002
% rate = 68/87 * 100% = 78.16%
44 multiplied by 87 is 3,828.
the range is also known as the IQR or inner quartile range's. The inter quartile range is the difference between the upper quartile and the lower quartile.heresy a good example.Example:18 27 34 52 54 59 61 68 78 82 85 87 91 93 100~First find the median -----> 68~then the lower quartile --> 52~next the upper quartile --> 87after you find these you may subtract the lower quartile (aka UQ) from the upper quartile (aka the UQ)In our case the IQR = 87 - 52 = 35.

87% of 46 = 0.87 * 46 = 40.02.Assuming you can only score whole marks then you will need to score 41 out of 46 to be certain (although 40 out of 46 would also be rounded up to 87 as the nearest whole percentage, which might be done.)
