Once there came many birds to a pond. There were certain number of lotus flowers in the pond. If each bird occupied one lotus one bird was left alone without any flower. If two birds sat in a flower one
Latest Answer: Let no. of birds is "b" and no. of lotus be "l" Now, a/c to first condition--> b = l+1 & a/c to snd condition--> b/2 = l-1 Solving above equations, we get, No. of Bird=4 & No. of Lotus = 3 ...
A pipe can fill a tank in 3 hours due to leakage it takes 3.5 hours to fill the same tank then how many hours will the leakage can empty the tank
Latest Answer: Let the tank be 1 ltr. It takes 180 min(3 hr) to fill this tank.Hence 1 min's work is 1/180After the tank got a hole in it, it takes 3 and 1/2 hrs ie.. 210 min.hence work expended in 210 min is 210*1/180=7/6Hence extra work spended due to hole is ...

Ans:::::::1.Two coins one with HEAD IN BOTH SIDES and the other coin HEAD IN ONE SIDE AND TAIL IN THE OTHER SIDE is in a box,a coin is taken at random and FOUND HEAD IN
When Arthur is as old as his father Hailey is now, he shall be 5 times as old as his son Clarke is now. By then Clarke will be 8 times older than Arthur is now. The combined ages of Hailey and Arthur are
Latest Answer: Let Age of Haley is = H, Arthur is = A, Clarke =CA+H =100 ---------------(1)H=5C ---------------------(2)(H-A) + C = 8A ----------- (3)Solving them gives H = 1500/17 , A = 200/17, C = 200/17 ...
A car is traveling at a uniform speed. The driver sees a milestone showing a 2-digit number. After traveling for an hour thedriver sees another milestone with the same digits in reverse order. After another hour the driver sees another milestone containingthe same two digits with a zero in between(0). What is the average speed of the driver.
Ans:
Let 10'splace digit is x and unit's place digit y
First milestone : 10x+y
Second milestone : 10y+x
Third milestone: 100x+y
Since the speed is uniform so
Distance covered in first Hr = Distance covered in Second Hr
(10y+x)-(10x+y) = (100x+y)-(10y+x)
After solving, we get ----> y=6x but since x and y are digits so only possible combination is x=1 and y=6,
So average speed = 45 KM/HR

My son is half of my age & was 1/3rd of my age 10 yrs back. What is my present age?
let the fathers age be f and son's age be s
s=.5f => f=2s..................1
(f-10)/3=(s-10) => f-10=3s-30
3s-f=20.............................2
solving 1 and 2
we get son's age as 20 and fathers age as 40
