Meghana and Deepti run in opposite directions from a point P on a circle with different but constant speeds. Meghana runs in the clockwise direction. They meet for the first time at a distance of 900 m in the clockwise direction from P and for the second time at a distance of 800 m in the anticlockwise direction from P. If Deepti is yet to complete 1 round, then the circumference of the circle is
(a) 1200m (b) 1250 m (c) 1300m (d) 1700m

guys i have seen many DI sets in which exact value is not given, not in any coaching center mocks but in actual cat papers viz 00 and before, can we expect such questions this year? if yes, how to solve? @scrabbler
Mr. Mehta distributed 100 silver coins amongst his four children such that the average of the number of coins received by his three sons is same as the number of coins received by his only daughter. The ratio of the number of coins received by two of his sons is 1 : 7. If the daughter received the second highest number of silver coins and if each child received more than one silver coin, then what could be the maximum possible number of coins received by any of the four children?
