9) Answer -> D

B - 40c / sec
A - 10c/sec
T - 2c/sec => 120c/min


Bus trip problem :

Answer - C

Working backwards,

If r = 45, t = 450/45 = 10hrs

now if new R = 45 + 5 = 50, new time = 450/50 = 9hrs

Satisfies, hence C


Stock market - well the values are missing !!


19) Answer - A

Can be deduced that:

M = 6n+1 (n is an integer > 0)
N = 6k + 3 (k is an integer > 0)

so (M + N) = 6(n +k) + 4, in other words (6L + 4) - L is an integer > 0

From the answer choices, only A violates this condition.


20) initial - y/r

new amt = y/r-x

so additional per student => y/r-x - y/r => xy/r(r-x)
