File transfer Question
A file is transferred from one location to another in ,buckets,. The size of the bucket is 10 kilobytes. The bucket gets filled at the rate of 0.0001 kilobytes per millisecond. The transmission time from sender to receiver is 10 milliseconds per bucket. After the receipt of the bucket the receiver sends an acknowledgement that reaches sender in 100 milliseconds. Assuming no error during transmission,...

In these type of questions,formula used isgain%=(Error/(true value-error))*100so 300/47=error/(True value-error)*1003/47=error/(1000-error)on solving u get error =60 if error is sixty that means he is using a weight of 1000-60=940gm

Numerical Ability
A super fast bus of KSRTC starting from 'Trivandrum' and reaches 'Attingal' in 45 minutes with an average speed of 40 km/hr. If the speed is increased by 10 km/hr how much time it will take to cover the same distance?(a) 34 minutes (b) 36 minutes (c) 38 minutes (d) 40 minutes
dinesh_madhu623
- Feb 11th, 2010
Answer is 36 mins We can approach the problem as followsFirst we have to find the distance we can do so byspeed = 40Time = 45 minshence dt = speed * ttdt = 2 * (15)dt = 30Now the speed can be increased by 10 now the speed is 50tt = dt/speedtt = (30/50) * 60tt = 0.6 * 60tt = 36.0

B) 36 mind=s*ts=40 km/hr=40/60km/mint=45mind=(4/6)*45=30kmnow increased speed= 50 km/hr=50/60 km/mind=30 kmt=d/s = 36 min

seaplane
A ship leaves on a long voyage. When it is 18 miles from the shore, a seaplane, whose speed is 10 times that of the ship is sent to deliver mail. How far from the shore does the seaplane catch up with the ship?
souravray_88
- Feb 7th, 2010
Let speed of the ship be 1 mile/hr. then speed of the seaplane is 10 miles/hr. so, to travel 18 miles he seaplane requires 1.8 hrs. and in this 1.8 hrs. the ship has travelled 1.8 miles more. Therefore seaplane catch up with the ship at a distance of (18+1.8)=19.8=20 miles approx. from the shore.

Ans is 20milesexplanation:the seaplane travels 10 miles when ship travels 1 mile.hence the seaplane travels 20 miles from shore when the ship is at 20 miles

I think that C doesn't define any opeartor for exponential function. It rather provides us with a pow(number, number_to_the_power) function that helps us to do the exponential opearations.

Unbelievably, there is no built-in exponentiation operator in C. Instead, there is a library function (pow) which carries out this operation.

Some are 1 kg weights and some are 2 kg weights. The sum of the weights is 260.What is the number of 1kg weights?
Ans : 40

There are a total of 150 weights. Let the number of 1 Kg weights be 'x'. Then the number of 2 Kg weights is '150 - x'. The sum of the weights is 260 Kg. ie [x * 1 + (150 - x) * 2] = 260. By solving this you will get 'x' as 40.

The answer is 4
Divide Coins As 27 27 26
now weigh 27 and 27 keeping on both sides of pan u will get the less one
and if both sides are equal then group that has 26 coins has the coin that is counterfiet...
if u get 27 as result divide it in 3 groups
9 9 9
and weight it
keep two groups on two sides of pans and get the result of both sides are equal then the group 9 which was not kept on the pan has the coin which is counterfiet....
now 9 is divided as in 3 groups as
3 3 3 and weigh again and get result
now divide 3 as
1 1 1 and get the coin..
in start if u get answer as 26 divide as 3 groups
9 9 8
wiegh by keeping 9 on both sides and get answer if both are equal then 8 is ans
if 9 is ans again divide as 3 3 3 and then 1 1 1 and get coin...
