hint : take r as 3/2 and 4/3 and u will get 3 more series
Let f(x) be a polynomial of degree 51 such that when f(x) is divided by (x – 1), (x – 2), (x – 3),...and (x – 51), it leaves 1, 2, 3,... and 51 respectively, as the remainders.

above case hav ratio as natural no..but ratio cud be fraction too..
Ramesh and Suresh are running on a circular track of length 1200m in opposite direction. everytime they meet, they exchange their speed as well as directions. what is the shortest distance btw their 13th and 23rd meeting points, if the ratio of their speeds is 1:5? a) 200m b)400m c) 800m d) 1000m

52? when you divide by x-1 it means if you substitute x=1 in f(x) you get 1 i.e f(1)=1;f(2)=2....f(51)=51

In three distinct regular polygons, it is known that the measure of the internal angle of one regular polygon exceeds the measure of the internal angle of the other two regular polygons by 15° and 27° respectively. Furthermore, the sum of the measures of the external angles of all the three regular polygons is 177°. What is the sum of the number of sides of all these three regular polygons ?

look at 13th and 23rd meet the speed doesnt change.. but the catch here is the direction.. Now see the pattern for the distance R will travel 1st meet 1/6*1200=200 2nd meet 5/6*1200=1000(remember this is in opposite direction so it is 800 in the opposite direction from the starting point or 400 in the normal direction from the starting point) 3rd meet 1/6*1200=200. Now he is at 600 from the starting point 4th meet 5/6*1200=1000. Now he is 400 in the opposite direction from the starting point or 800 in the normal direction. 5th meet 1/6*1200=200. Now he is 1000 from the starting point. 6th meet 5/6*1200=1000. Here he will be at the starting point.
therefore at every 6th meeting R will be at the starting point. So for 13th meet he will be 200 from the starting point and for 23rd meet he will be 1000 from the starting point. but the shortest distance will be 1000-1200 and 0-200 so 400.

It is clear that they will meet at 6 points = sum of ratios of speeds l/6, 2l/6,3l/6,4l/6,5l/6 and l - those meeting points
first meeting at l/6 and start counting 13th meeting will be at the same place i.e l/6
similarly 23 meeting will be at l/6 but in opposite to the 13th one
