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 .

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.

The vector equations of two lines L_1 and L_2 are respectively vec r=17hat i–9hat j+9hat k+ lambda(3hat i +hat j+ 5hat k) and vec r=15hat –8hat j-hat k+mu(4hat i+3hat j) I L_1 and L_2 are skew lines II (11, -11, -1) is the point of intersection of L_1 and L_2 III (-11, 11, 1) is the point of intersection of L_1 and L_2. IV cos^-1 (3/sqrt35) is the acute angle between _1 and L_2 then , which of the following is true?

A 1-L flask contains some mercury. It is found that at different temperature, the volume of air inside the flask remains the same. What is the volume of mercury in the flask, given that the coefficient of linear expansion of glass =9xx10^(-6)//^(@)C and the coefficient of volume expansion of Hg=1.8xx10^(-4)//^(@)C ?
