next one->the duration of a rauilway journey varies as the distance and inversely as the velocity ;the velocity varies directly as the square root of thwquantity of coal used per km and inversely as the number of carriages in the train.in a journey of 50km in half an hour with 18carriages ,100kg coal is required.how much coal is consumed in a journey of 42km in 28 mins with 16 carriages.
pls tell me ur ans.i got the equation /=/42*16.
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.
number of ppl=n
wn=(0.8w) * N
or 25% rise in ppl.
There is a shortcut to this, that I am unable to recollect.I am confused. its something like 20%=1/5(x/y) so 20% fal corrsponds to x/(y-x) sumthin like this...please explain.
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)=dist/b - 9
If i take b/dist as x and s/dist as y , i am getting a quadratic..the process gets too long...what to do ?
If question were as below?

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.?
whats the eaxt formula for euler of a number.
where all is it used?
