Read Solution (Total 1)

sum of scores of top 3 students = 25*75-22*73 = 269
sum of score of first and third student = 269-89= 180 as second highest score is less than 90.
For least highest, score of third ranker should be max possible which is 88.
Then score of highest ranker = 180-88= 92

Note .. solved assuming that all three rankers got integer marks only.

Amit and Bharat run around a circular track running in the same direction. They started at the same point and at the same time. Amit’s speed is four times Bharat’s speed. Both of them have different number of tokens with them. Whenever one of them overtakes the other, the former gives the latter as many tokens as the latter already had, so that the number of tokens with latter doubles. However, if a person overtakes another at the starting point, then the latter gives half his tokens to the former. There is no exchange of tokens if a fractional value is encountered. It is known that Bharat started with one token and Amit finished with 70 tokens after a certain number of rounds. Which of the following could be the number of tokens Amit started with? 1. 1012. 1023. 1284. 180
