	Recreation Bill	School Bill	Tax Bill
Dev	√	×

Shahid	×
Sukhdev	√		×

Exactly one member of the council votes for the tax bill. Sukhdev votes against the tax bill. So, Dev and Shahid can’t vote for or against the tax bill in the same way. Hence, option (a) is ruled out. Shahid votes against and Sukhdev votes for recreation bill. Hence, option (b) is ruled out. Shahid and Sukhdev can’t vote the same way on the school bill as in option (c).

$m = \frac{f}{f + u} + \frac{- f}{- f - f} = + \frac{1}{2}$

v = \frac{u f}{u + f} \Rightarrow v = \frac{- f \times - f}{- f - f} = \frac{f^{2}}{- 2 f} = \frac{- f}{2}

∴

dist of image from optical cnetre =

\frac{f}{2}

Note that from statements, (I), (IV) and (VI) we can make out that W3 lives in New Delhi. Now from (V), we can make out that W1 is not the dancer; and from (II), since W3 lives in New Delhi, she is also not the dancer. Therefore, W2 is the dancer and lives in Goa. Also from (VIII), W2 is married to Malkhan. Now since W3 lives in New Delhi and W2 in Goa, it is obvious that W1 lives in Mumbai and from (IX), she (W1) is married to Pankaj. Hence, the result is as follows.

Goa

From the given information we can conclude that (P3) and (P4) are at seat numbers 7 and 6, respectively. And (P11) is the only person between (P3) and (P10) while (P1) is opposite to (P11). Hence, (P1), (P11) and (P10) must be at seat numbers 5, 8 and 9 respectively.

A body of mass M moving at speed V₀ collides elastically with a mass ‘m’ at rest. After the collision, the two masses move at angles q₁ and q₂ with respect to the initial direction of motion of the body of mass M. The largest possible value of the ratio M/m, for which the angles q₁ and q₂ will be equal, is:

$M V_{0} = M V_{1} + m V_{2} . . . . (i)$

∴ M V_{1} = m V_{2}

$M V_{0}^{2} = M V_{1}^{2} + m V_{2}^{2}$ . (iii)
