In a large hall there are `4x^2` rows of benches. If each row has `5x^2y^3` benches and each bench can accommodate `x y^2` person, determine the total number of persons if its is full up to its capacity.

In a class-room there are 2x rows of benches. If each row has 3xy beneches and each bench can accommodate x students,determine the number of students in the room if it is full up to its capacity.

If there are x rows of chairs and each row contains x^(2) chairs.Determine the total number of chairs.

There are benches in a classroom.If 4 students sit on each bench,then three benches are left vacant and if 3 students sit on each bench,then 3 students are left standing. The total number of students in the class is (a) 36quad (b) 42 (c) 48 (d) 54

In a room there are x^(2) rows of chairs and each row contains 2x^(2) chairs.The total number of chairs in the room is 2x^(3)(b02x^(4)(c)x^(4)(d)(x^(4))/(2)

There are 'y' a mango trees in each row in an orchard. If there 'x' rows, then how many mango trees in all are there in the orchard.

Students of a class are made to sit in rows of equal number of chairs. If number of students is increased by 2 in each row, then the number of rows decreases by 3. If number of students is increased by 4 in each row, then the number of rows decreases by 5. What is the number of students in the class?

To get a maximum current in an external resistance of 8Omega one can use m rows of n cells (connected in series), connected in parallel. If the total number of cells is 64 each having an e.m.f. of 2V and interanl resistance of 2Omega , then calculate the number of cells in each row and number of rows.

A conical tent can accommodate maximum 176 persons, if 1.26m^(2) floor area is given to each person. The height of the middle pole of the tent is 6m. If the tent is occupied by the persons to its full capacity, find how many m^(3) of air is available to each person.

For the parade there are y students in each row and x such rows are formed . Then how many students are there for the parade in all ?
