3.32.75.............
@sscjindabad said:Explain!!
let, length of her shadow is x.
in 4 sec d gal cover d distance 4.8m
now one rightangle made by d lamp & total dsnce covered by girl plus length of shadow and other is fored by hieght of the girl and her shadow.
by comparing the 2 triangle we can write,
(0.9/3.6)= (x/4.8)
x=1.6m
so the length of the shadow is 1.6m
@ansh099 said: JS-M bro lcm will be 2520 ... which is completely divisible by all numbers so in order to obtain remainder 1 ....we will add 1 to our obtained lcm.. thus the ans will be 2521. correct me if i m wrong.
Bhai instead of adding 1 u shud subtract 1 n answer wud be 2519

Overlapping time = n + n/11 hrs
where n is the no of hrs passed .
here n=3
so overlapping time = 3+ 3/11 hrs = 3 hrs 180/11 minutes = 3 hr 16.36 mins

@sscjindabad said: to all the puys:I have not yet recieved my admit card though it is available on the site and it has mentioned only post pref n no state pref as was the case in the PDF file containing the marks secured...Its really bothering me ....Comment solicited...
bro, I received my admit card yesterday. No post preferences or state preferences are mentioned in it. In fact, none of my friends haven't. 
@sscjindabad said:Explain!!
first apply formula of tan in triangle ABC then in triangle DEC and then from the equations u can calculate the value of x i.e the length of her shadow

i took when both In a straight line ............us hisab se thek hai kya ....plz check??

in tan^2 A= 2tan^2 B + 1 then cos^2 A + sin^2 B =?

percentage error in calculating SA of cube = [{(10.02)^2 - 10^2}*6/{10^2}*6]*100

ya... overlapping of minute and hour hand, it takes place at 3:16 PM.
or
because it takes every single movement of hour hand after 10 minutes when it reaches 03.16pm it aligned first.
