Optical Cable Laying Cost
A optical 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) 3900
(c) 1800rajpalwindersmvdu

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

anirban_goswami- Member Since Feb-2008 | Mar 11th, 2008
No. of cats = x(say)
Therefore, no. of mice killed by each cat = 999919/x (since, they killed equal no. of mice)
Now, given that
(999919/x) is greater than x, i.e
999919/x > x, implies x*x<999919
Therefore, x < 999.95(approx). Now, the only no. which is nearest to but less than 999.95 and is a factor of 999919 is 991.
Thus, x = 991 and no. of mice = 999919/991 = 1009.amith.aec
- Oct 29th, 2010
Observing the num 999919 which is the total num of rats being eaten..we can write it as?(1000000-81) = ? (1000^2-9^2) ? = ? (1000+9)(1000-9) ? = ?(1009)(991)so total num of rats killed =(1009)(9...
