23. On selling a bat at 5/7th of its marked price, the store earns 15% profit. What is the profit earned if it is sold at marked price?

Reply Like? Yes | No

Devendra Marghade 10 years ago

61%

If marked price=x, then 5x/7 is 115% of the actual cost,so x=115*x/(5x/7)=161 of the actual cost.
Hence profit earned=61%.

opyion is A)
Suppose he move 4 km downstream in x hours. Then,

Speed downstream = 4 km/hr.
x
Speed upstream = 3 km/hr.
x
48 + 48 = 14 or x = 1 .
(4/x) (3/x) 2
So, Speed downstream = 8 km/hr, Speed upstream = 6 km/hr.

Rate of the stream = 1 (8 - 6) km/hr = 1 km/hr.

A thief is spotted by a police man from a distance of 200m. When the police man start chasing the thief also starts running. If the speed of the thief be 16km/hr and that of the policeman be 20km/hr, how far the thief will have run before he is overtaken?

Reply Like? Yes | No

animesh 8 years ago

the separation initially is 200m ,
final separation is 0m,
so,
relative distance travelled is 200m.
velocity of police is 20kmph
velocity of theif is 16kmph
relative velocity is 4kmph.
so using v=d/t
we get,
t=d/v
=> 0.2/4
=> 1/20hrs
=> (1/20)*60mins
= 3 minutes.

here we have a*b*c*d=126
a*c=19
and in brackets a condition is given, by that condition we get a+b+c+d=10a+c=19
so by equating both sides we get in tens place a=1,c=9 in units place
b*d=126/9=14
b+d=9
so by solving we get the values of b &d as 7 &2 respectively
in the question they asked the diffrnce of hundreds and tens so 7-2=5.so 5 is the correct answer

a team 80% of games it played.it played 5 more games of which it won 3 and lost 2 .its loss percentage changed to 25%.how many games did played overall??

20 games

If initially games played=x, then games won=(80/100)*x=0.8x and lost=(20/100)*x=0.2x
When 5 more games are played it won 3 and lost 2, so total won=0.8x+3 and lost=0.2x+2
As loss percentage is 25% of the total game played, so (0.2x+2)/(0.8x+3) =25/75, x=15
Overall games played=15+5=20

A can do a job in 20 days. He is 20% less efficient than B but 20% more efficient than C. They will all do the job in how many days working together?

Ans=6 18/37

1 day job of A=1/20, B=(1/20)*(100/80)=1/16 and C=(1/20)*(100/120)=1/24
So working together ,days required to complete the job=1/[(1/20)+(1/16)+(1/24)]=240/37=6 18/37

t=d/s
vinay-3x
Shyam-4x
distance to be covered by vinay=500-140=360
distance to be covered by shyam=500m
time taken by vinay=360/3x
in this time distance covered by shyam =
4x*360/3x=4*120=480m
So in the time Vinay has covered complete 500m , shyam has covered only 480m .Thus Vinay wins by 20m.

6

minimum common factor of 16 and 24 is 48, so 3 tiles along 16 units edge and 2 tiles along 24 units edge can form a square.
