Direction: 8 people are sitting in 2 rows, 4 in each row. A, B, C, D in first row faces South, not necessarily in the given order & each likes a color from the set: Red, Yellow, Blue and Green. Similarly, K, L, M & N sit on the second row facing North & each likes a color from the set: Black, White, Orange & Pink. Therefore, people in two rows face each other. Further information is given below.
N sits adjacent to L and likes white color. Person who likes pink color sits to the left of L. M sits opposite to A, who likes Green color. C does not like red color. N sits opposite to B who likes yellow color. L sits to the opposite of the person sitting adjacent to the person who likes Green color. The people who like Green and Red sit at edges.
Based on the given information, answer the following questions.Two like parallel forces $P$ and $Q (P > Q)$ act on a rigid body. If the force P is displaced parallel to itself through a distance d, then the resultant of the forces $P$ and $Q$ would be shifted by a distance
1). $\frac{P}{{P + Q}}d$
2). $\frac{P}{{P - Q}}d$
3). $\frac{Q}{{P - Q}}d$
4). $\frac{Q}{{Q - P}}d$
Directions: Study the following information to answer the given questions:
A, B, C, D, E, F, G, and H are seated in a straight line facing north but not necessarily in the same order. B sits third to the left of E. Neither B nor E sits at the extreme end of the line. Only one person sits between E and G. G is not an immediate neighbour of B. C sits third to the right of A. A is not an immediate neighbour of B. Only one person sits between H and D. C is not an immediate neighbour of H.In a family there are several brothers and sisters. Every 2 boys have brothers as many as sisters and each girl has 2 brothers less than twice as many brothers as sisters. Now find the number of boys and girls.
A). 8 , 6
B). 6 , 8
C). 6 , 8
D). 12 , 10
A chord AB of a circle C1 of radius (√5 + 2) cm, touches a circle C2 which is concentric to O. If the radius of C2 is (√5 - 2) cm then length of AB is –
1). \(4\sqrt {20}\) cm
2). \(4\sqrt[4]{{20}}\) cm
3). \(2\sqrt[8]{{20}}\) cm
4). \(4\sqrt[8]{{20}}\) cm
