The probability that a student selected at random from a class will pass in Hindi is 4/5 and the probability that he passes in Hindi and English is 1/2 . What is the probability that he will pass in English if it is known that he has passed in Hindi ?

study the following information carefully and answer the questions given below it. An exhibition is open for pubic since 9 am till 3 pm and again since 4 pm till 10 pm in a day. There are 12 batches of 1 hour each. The entry ticket bears a pass code made up of seven words, which changes every hour following a particular rule. The pass codes for 4 pm to 10 pm are same as those for respective hours during 9 am to 3 pm i.e., the pass code for 4 pm to 5 pm is same as that of 9 am to 10 am and so on. Following is an illustration of the code and steps of rearrangement for subsequent clock hours. First batch : 9 am to 10 am (4 pm to 5 pm) Pass code : dig more and you will find water Second batch : 10 am to 11 am (5 pm to 6 pm) Pass code : and dig find you water will more Third batch : 11 am to 12 noon (6 pm to 7 pm) Pass code : find and will you more water dig and so on. If the pass code for 5 pm to 6 pm is 'out in above over the field end', what will be the pass code for 1 pm to 2 pm ?

Ratio of the fares of First ,Second and Third class catogory of a train , between two stations is 10:7:2 and the ratio of passenger travelling in these category is 4:9:17 respectively .If the fare is increased by 1/4 in First class , 1/8 in second class and decreased by 10% i Third Class and the ratio of number of passenger in the category remains same .If the total amount received of Rs. 60590 , then find the total amount received from thrid class category .

Between two railway staions the fare of 1^(st), 2^(nd) and 3^(rd) class are in the ratio 8:6:3. But later on the fare of 1^(st) and 2^(nd) class is decreased by (1)/(6) and (1)/(12) spectively. In one year the no. of passengers of 1, 2nd and 3rd class are in the ratio for 4:9:24. If total tickets amounting Rs 355600 are sold then find the fare of all 3rd class.

Railway fares of 1st, 2nd and 3rd class between two stations were in the ratio of 8 6 : 3. The fares of 1st and 2nd class were subsequently reduced by 1/6a n d1/(12) respectively. If during a year the ratio 12 between the passengers of 1st, 2nd and 3rd classes was 9 :12 : 26 and the total amount collected by the sale of tickets was Rs, 1088, then find the collection from the passengers of 1st class.
