If `(p+q)/(r+s)=(t+u)/(v+w)`. Express v in terms of p,q,r,s and w.

Text Solution

Verified by Experts

`(p+q)/(r+s)=(t+u)/(v+w)`
`implies(p+q)(v+w)=(t+u)(r+s)`
`impliesv(p+q)=(t+u)(r+s)-w(p+q)`
`impliesv=((t+u)(r+s)-(p+q)w)/(p+q)`

Directions: Study the following information carefully and answer the question given below: P, Q, R,S, T, U, V and W are sitting around a circle feeing the centre. T is second to the left of P and third to the right of V. S is second to the right of W, who is on the immediate right of T. Q is third to the right of U. Who is fourth to the left of R? 1) U 2) P 3) S 4) W 5) None of these

Direction: Study the following information carefully and answer the question given below. Eight people P, Q, R, S, T, U, V and W are sitting around a circle. All of them are facing the center but not necessarily in the same order. P is sitting to the second of T. S is sitting next to the left of R. U is sitting opposite to W. W is sitting third to the left of P. R is neighbour of neither W nor T. R is sitting opposite to Q. V is not a neighbour of Q. How many persons are sitting between Q and U when counted from the left of Q?
