Let x = rupees divided among b and cGiven x * 35/100=560x*65/100=560*65/35=> x = 10401040+ 560 = 1600and from the question we can say that a gets double of share which b and c together gets=> a's share is 3200

C's share = 560?which is 35/200 of total sum.Total sum be x (35/200) * x =560x=3200 Rs.

Let the height of the pole be hlet the distance at which the angle of elevation is 30 be x.then we havetan 15 is h/100+xtan 30 is h/xby solving we get x as 866and the height as 499.7 which is approx 500m

The height of the pole is 50 mappllying trigo, we get,.tan 15 = h/(100+y) ;tan 30 = h/y;solving above, we geth=50m

Fisherman's Day
A fisherman's day is rated as good if he catches 9 fishes, fair if 7 fishes and bad if 5 fishes. He catches 53 fishes in a week n had all good, fair n bad days in the week. So how many good, fair n bad days did the fisher man had in the week?
hydsarema
- May 24th, 2009
Let good days be xlet fair days be ylet bad days be zsince there are 7 days in a weekx+y+z is 79x+7y+3z=53since it is a 3 variable equation and we have only 2 equations we have to assume values for one of them.so let x be 1,2,3,4.putting x as 4 we get y as 1 and z as 2
pawansharma1987

If you want the answer quickly it can be done by generate and test method? x +y+z =7? 9x+7y+5z= 53hence x= 3 y =3 z=1 ans.

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) -
