The size of a program is N.And the memory occupied by the program is given by M=square root of 100N.If the size of the program is increased by 1% then how much memory now occupied?
Akshaya
- Sep 21st, 2007
Answer is 0.5% bcoz...take n=100 then memory m=sqrt(100n)=sqrt(10000)=100Increase n by 1% thenn=101 then memory m=sqrt(100n)=sqrt(10100)=100.5then memory will be increased by 0.5%

Cable Cost
A telephone cable is to be run from a junction point on the bank of a river 900 meters wide to an office 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.(a) 450(b) 1800(c) 2800(d) 2100(e) 2700

In a mixture, R is 2 parts S is 1 part. In order to make S to 25% of the mixture, how much r is to be added?
One Part
velusara
- Nov 19th, 2010
Ans = R should be added with 50%If r is 2 parts S is 1 part i.e 2/1 = 1 or 1+1 = 2so if s increases by 25% of 1 then it is 1.25 + 1.25 = 2.5 that is r
Prashant202185
- Sep 24th, 2008
Since R= 2 parts and S = 1 parts so % of s = 1/3*100 = 33.33%Let x of r is added to make S to 25%then 1/(3+x)*100 = 25 => 75+25x=100 so x= 1 ans

in a company 30% are supervisors and 40% employees are male if 60% of supervisors are male. What is the probability? That a randomly chosen employee is a male or female?
manoj004ece
- Nov 2nd, 2010
Many of them said answer is 0.4 but it s correct only when they ask what us
the problem of choosing male, but in question they have clearly given male or
female, so at any point of time if we choose an employee either it should be male
or female, so the prob s 1. This is correct answer

1) 450Since cost of putting cable on land is less than that under water.So we lay cable mostly on ground so best solution is 450

The output is zero because u is declared as a int type when we devide the 5 with 9 the result is 0 and multiply it with t-32, the total result is zero.There fore the option is b.

The correct answer is 38.5. this can be found out using area of sector formula pi*R^2*theta/360 pi*7^2*90/360 38.5sqm
rakesh8014

4 km/hr from A to B = s1
8 km/hr from B to A = s2
Speed = Distance/Times1 = d1/t1
s2 = d2/t2
s1/s2 = t2/t1 We need t1/t2 so,
Answer ratio is 2:1
Check if its correct..
