1) plug in numbers...that's the shortest way. first take d=2 and n=4 thus there are 2 multiples of d(2) i.e 2 and 4 that are equal to or less than 4. then try for 3 and so on. u will see the pattern.

2) formula for calculating this is percentage decrease = (change in assets/original amt of assets)*100. change is = 3. original amount = 74+3. this approximates to 4.

hope that's helpful
