Time taken by Magadh=288 min
Let total distance= D
so, speed of shramjivi Vs=D/320
speed of magadh Vm=D/288
Magadh starts 22 min before Shramjivi.
So, distance covered by magadh in this duration = 22*D/288
Now let after 't' min both the trains ...
after disc, SP = 0.9MP
MP = SP/0.9
1.17CP = 0.9MP = SP
MP = 1.17CP/.9
Profit% =( (MP-CP)/CP)*100
= 30 %(MP = 1.17CP/0.9):)
The 4th problem,
CP = 375;
SP=0.8*375, as it is sold at a loss of 20%.
CP as % of its SP = (375 / (0.8*375))*100 = 125%
9.48 am + 2hrs 42 mins -> 12.54 am
it shud b 12.30 am
so ur approach is also right.
do u hav the actual answer of this question?
Plz help me out with detail explanation , i knw the answer , interested in explanation , so i come to knw where i am wrong..
therefore time when they will meet = (133/(3*(10+9)))
where 10+9 = relative speed
they will meet after 2 hrs 20 mins after shramjivi starts off
therefore at 12:30
10:10 + 2hrs 20 mins...Am I correct plzz tell
According to me,
Speed of magadh = 10 km/hr
Speed of shramjivi = 9 Km/hr
Therefore total distance already travelled by magadh = 10 * 11/30 = 11/3
Distance left = 48 - (11/3)
speeds A = 4 units/min
B = 7 units/min
so, if A travels x units before meeting,
(x/4) = (22-x)/7
x = 8
so they will meet after 2mins, and rest for half min
now there speeds get doubled, so now they will meet at hal...
Let the distance between Patna & New Delhi be 48 km (LCM of 16 and 24 )
the time taken by Shramjeevi to reach New Delhi : 5 hrs 20 mins
the time taken by Magadh to reach Patna : 4 hrs 48 mins
so speed of Shramjeevi = 48 / (5+(20/60)) = 9 km/hr
speed of Magadh = 48 ...
Shramjeevi Express leaves Patna for New Delhi at 10:10 am and reaches New Delhi at 3:30 p.m. Magadh Express leaves New Delhi at 9:48 a.m. and reaches Patna at 2:36 p.m.If routes of both the trains are the same, then at what time will the trains mee...
And also for quantum quant......
but i think Quantum cat by s.k.verma is a far better book compared to the other quant books available in the market.
p.s.-my personal opinion having gone through both arun sharma and nishit sinha.
