Using section formula , show that the points A(7,-5),B(9,-3) and C(13,1) are colliner.

The ratio of boys and girls in sections A,B,C and D of class VI is especially.7:5,5:3,3:2 and 2:1. If the number of students in each of the sections is equal then maximum number of bys are enrolled in section A b.B c.C d.D D

There is a slab of refractive index n_(2) placed as shown. Medium on two side are n_(1) and n_(3) . Width of slab is d_(2) . An object is placed at distance d_(1) from surface AB and observer is at distance d_(3) from surface CD . Given n_(1)= air [ref. index =1] and n_(2) is glass [ref. index = 3//2 ], d_(1) = 12 cm and d_(2) = 9 cm,d_(3) = 4 cm . If object starts to move with speed of 12 cm//sec towards the slab then find the speed of image as seen by observer [given n_(3)= air =(ref. index =1 )].

Using the section formula,prove that the three pints A(-2,3,5),B(1,2,3) and C(7,0,-1) are collinear.

A, B, C, D, E, F, G and H are eight friends sitting around a circular table facing the centre. A sits second to the left of D, who is third to the left of E. C sits third to the right of G, who is not an immediate neighbour of E. H sits third to the right of B, who sits second to the right of G. Who is third to the right of E? 1) C 2) F 3) D 4) Data inadequate 5) None of these

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

A, B, C, D, E, F, G and Hare sitting around a circle facing the centre. B is 2^(nd) to the right of D who is 3^(rd) to the right of F. C is 2^(nd) to the left of A who is 2^(nd) to the left of. G is 3^(rd) to right of E. Who is to the immediate left of G ?
