A power unit is there by the bank of the river of 750 meters width. A cable is made from power unit to power a plant opposite to that of the river and 1500mts away from the power unit. The cost of the cable below water is Rs. 15/- per meter and cost of cable on the bank is Rs.12/- per meter. Find the total of laying the cab
Vaibhav Pate

Width of river = 750 metersplant from the power unit = 1500 metershence, the cable on the bank is 1500 - 750 = 750 meters.so, total cost = (750*15) + (750*12) = Rs. 20250/-

since the distance travelled is same st=(s+0.5)(4/5)ton solvin u will get s=2there is one more equationst=(s-0.5)(t+5/2)substitute s=2 in the above eq and find 't' u will get s=2,t=7.5 therefore d=st=15kmans:15km

A ship started from a port and moving with I mph and another ship started from L and moving with H mph. At which place these two ships meet.
Between I and J and close to J
shikhi
- Jul 23rd, 2007
From the port to the perticular distance is L.
So from simple maths, You can say that if?(I+H) mph distance can cover in 1 hour, then l distace cancover by L/(I+H) hours. -
A report consists of 20 sheets each of 55 lines and each such line consists of 65 characters. This report is retyped into sheets each of 65 lines such that each line consists of 70 characters. The % reduction in the number of sheets is closest to a) 20 b) 5 c) 30 d) 35

20% is d ans20*55*65 = 71500 charsLet the number of sheets required be x here.Hence, x*65*70 = 71500 charsor x = 71500/65*70 = 15.71 = 16 sheets(approx)hence % reduction in sheets = 20%
