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,...

Power cable question
A power cable is to be run from a power plant on the bank of a river 900 meters wide to a factory that is located 3000 meters downstream on the opposite bank. If the cost of laying cable under water is Rs. 5 per meter and that of laying overhead on land is Rs. 4 per meter, find the point downstream where the cable is to cut across the river.

I do not think it is complex. They give cost to plant the cable in ground and water both also
Let assume the length across the river is x;By given cost 5x=4*3000+5*900so x=3300 3300/2=1650so the point is 1650m from x axis, and 450m(half of distance bet banks) from y axis(450,1650) -

Dealer gains (300/47)% for a Kg.Let cost price is Rs100i.e he gains Rs(300/47) for a Kgi.e his selling price is Rs(100+300/47)Now If he used proper weight then selling price of Rs100 would account for...

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
