The average mathematics marks of two Sections A and B of Class IX in the annual examination is 74. The average marks of Section A is 77.5 and that of Section B is 70. The ratio of the number of students of Section A and B is

A long, straight, hollow conductor (tube) carrying a current has two sections A and C of unequal cross sections joined by a conical section B. 1,2 and 3 are points on a line parallel to the axis of the conductor. The magnetic fields at 1,2 and 3 have magnitudes B_1, B_2 and B_3 . Then,

Read the data given below and answer the quesitons based on it. There were 3 sections namely A, B and C in a test. Out of three sections, 33 passed section A, 34 students passed in Section B and 32 passed in Section C. 10 students passed in Section A and Section B, 9 passed in Section B and Section C, 8 passed in Section A and Section C. The number of students who passed each seciton alone was equal and was 21 for each section. How many passed all the three sections ? A. 3 B. 6 C. 5 D. 7

If the average marks of 30 students of section A is 55 and the average marks of 30 students of section B is 60 ,then find the combined average of both the sections.

If the average marks of 30 students of section A is 55 and the average marks of 30 students of section B is 60 ,then find the combined average of both the sections.

If there are two section of class SSC in Mother's Coaching ,section A says if some of students of section B will take transfer and join us then ratio of students of class A to that of class B becometes take transfer of section B then this ratio becomes 4:7 , then among option which can be a value of number of tranfers .
