Let the three numbers in a G.P. be a/r, a, ar
a/q
(a/r)*(a)*(ar)=216
=>a^3=216
=>a=6
&
(a/r)+a+(ar)=21
put a=6
6/r+6+6r=21

A car is travelling at a uniform speed
The driver sees a milestone showing a 2 digit num
After travellingfor an hour the driver sees another milestone with THE SAME DIGITS IN REVERSE ORDER
AFTER ANOTHER HOUR THE DRIVER SEES ANOTHER MILESTONE CONTAINING THE SAME TWO DIGITS
WHAT IS THE AVERAGE SPEED OF THE DRIVER?

Reply Like? Yes | No

(10 years ago)

the first milestone seen by the driver is 2 digited. let it be ... 10x + y ..(1)
After 1 hr
the second milestone is in reversed order. it must be ... 10y + x ....(2)
again after 1 Hr
the third milestone having same digit bt their is zero btween the to digitsit is given as ... 100x + 0*10 + y = 100x + y ....(3)
from eqn 2 and 3, we get
{(100x + y) - (10y + x)}/1 = speed of the car .... {Distance = speed * time}
therefore speed of the car = 99x - 9y .. (4)
from 1 1nd 2 ,we get
9y - 9x = speed of the car ....(5)
from eqn 4 and 5,we get
9y - 9x = 99x - 9y
or y - x = 11x - y
or y = 6x ... (6)
substituting this value in the eqns 1 and 2, we get
10x + 6x = 16x (the first milesztone)
10*6x + x = 61x (the second milestone)
Speed of the car = (distance between two milestone)/time
= (61x - 16x)/1
= 45x km/hr

=>49^15/34
=15^15..... 49/34=15 rem
(15^3)5/34
