Hi Sam, Well there's no shortcut to this and you have to do the calculations. However you can reduce the slightly by some smart work. The first term has to be divided so the result would be 14508. Now instead of dividing the second term by 25, you can rather take 14508 to be second term and divide it by 5.( We just took 5 common from numerator and denominator in second term). Yu will get 2901. Now instead of performing the division on 3rd term, divide 2901 by 5. You will get 580. Now add these values and you have your result. Note that I have assumed that all these terms are greatest integer less than equal to x. If that is not the case then it is not worth attempting this question in exam.
