Is it ok for a person to quit work to prepare for CAT? Would that create a negative impression on the panel,conveying that the candidate is a bad manger of time and hence would not be suitable for the role of a manager?

50! is divisible by 144^n...what is the max. integral value of n?

144 = 2^4 * 3^2...difficult to decide whether 3 or 2 will be the deciding factor...

count 2s

50/2=25

25/2=12

12/2=6

6/2=3

3/2=1

sum=47

answer = 47/4 = 11.(hey why did ya again divide by 4 here?)

thanks ya.

thanks ya.

next one->pls tell me ur ans.i got the equation /=/42*16.

i.e t=kd

=k/v

so tv/d=k

v=k sqrt(c/km)/carr

t.sqrt(c/km)/d.carr=k

hi guys..there is a concept which goes

suppose ders a fal of 20% in the wages , by how much percent shud the no of emploees be increased to keep the total wages const.

the thought process is 20% fall in wages w results in 0.8 w.

wages=w

number of ppl=n

wn=k(const)

wn=(0.8w) * N ...

A crew can row a certain course up the stream in 84 mins.they can row the same down stream in 9 mins less than they can row it in still water.how long would they take to row down down the stream?

dist=dist of stream

b=speed of boat

s=speed of stream

dist/(b-s)=84

dist/(b+s)=dist/b ...

3 bulbs flicker together after 1080 secs or 18 mins

as per the clock the time wshould be 8:18:00

but clock loses 2sec per min

so ifor 1080 secs or 18 mins it loses 36 secs

so clock shows 8:17:24

3 bulbs flicker after 120 sec, 72 sec and 135 sec.

If they flash at 8.00.00 hrs simultaneously accdg to a watch that loses 8 secs evry min, when will tehy flash again simul.?
