yarr it's not as difficult as it looks

the fastest guy takes 6 days if he is handeling alone ,but it is not hence option for 6 and 3 days is eleminated.

the slowest guy takes 8 days rest all are are fast so there is no way target will go over to 9 days  

hence the only option is 7 days

let thet speed of ship is =v

so seaplane speed must be=10v

let seaplane catch the ship in t time

so in t time ship moves x distance

so x/v=(x+18)/10v

x=2

so distance =18+2=20

48 is the answer.

84

Here is the solution in details:Say father's age is x,and son's age is y.we have two variables.We have two equations also.As son's age is half the father's age.So y=x/2 or x=2y---------------(1)Now yo...

let total age of father = x

let total age of son =y

then y=x/2

as father was batchlor for 1/7 of his life & got son after 5 years of his merrige

& dies after 4 years of his son's deth

then

x/7 + 5 + y + 4 =x

by solving the equation

father x=27.2 years

son y=13.6

for any matrix take thius formula  4*4=1^2+2^2+3^2+4^2

similarly for 8*8==1^2+2^2..........+8^2=204

We discovered that there are 204 squares on the board We found that you would add the different squares - 1 + 4 + 9 + 16+ 25 + 36 + 49 + 64.Also in 3*3 tic tac toe board what is the total no of square...

(x+10)=(x+35)/2

soling the eqn we get x=15

speed limit= 15 miles/hr.

160 miles= 330 min

1 mile = 330/160

80 miles=(330*80)/160=165 min.

in 165 minutes wind will travel 80 miles in standard temprature and pressure

Volume of rectangle:- l*b*h= 8*11*2=176 Volume of rod:- (22/7)*(r^2)*l=(22/7)*(4^2)*lSolving(22/7)*16*l=176(22/7)*l=11l=7/2l=3.5 inchesThe length of rod is 3.5 inches

L = 3.5" is the answer.

138 matches will delete low performances and last one will be champion

SO 138 MATCHES WILL DO

the answer is 138 matchesexplanation:since one player gets a bye in each round,he will reach the finals of the tournament without playing a match.therefore 137 matches should be played to detemine the...

product of roots of eqn a*x^2+b*x+c=0 is c/a 
here product of roots =1 
=> k/5=1 
=>k=5
