87 men can do a certain job in 94 days. The same job is instead started by one man on the first day and then, from the second day onwards, each day some more persons join the work. If the number of persons joining on the nth day (n ≥ 2) is twice that of those joining on the (n − 1)thday, in how many days will the job get completed? 13 or 14?? Not sure about the answer
Two persons, A and B, start simultaneously from starting point on a circular track and drive around the track in the same direction, with speeds of 29 km/hr and 19 km/hr respectively. Every time A overtakes B (anywhere on the track), both of them decrease their respective speeds by 1 km/hr. If the length of the track is 1 km, how many times do they meet at the starting point before B comes to rest? @trawler @DreamerIIMC

Solution please !! @TanujA3 The series of numbers (1,1/2,1/3,1/4......1/1972) is taken. Now two numbers are taken from this series (the first two) say x, y. Then the operation x + y + x.y is performed to get a consolidated number. The process is repeated. What will be the value of the set after all the numbers are consolidated into one number? (a) 1970 (b) 1971 (c) 1972 (d) None of these
As a cone rolls on the surface of a table, it traces a circular arc cetered on the vertex. While making a full circle, it rotates 17 times. Find the ratio of the height of the cone to its radius.
