My age : 10x+y
Son age : 10y+x
so 10x+y = 10y+x
10x+y-1 = 2(10y+x-1)
x = (19y-1)/8
for y=3
(19y-1) is completely divisible by 8
so x = 7
So my present age : 10*7+3 = 73
son's age : 10*3+7 = 37

The formula to find the angle between hour hand and min hand is :
suppose hour is represented as H and minutes is represented as M then the formula is
Angle = 30 H -11/2M
|
| Author: varun sharma 10 Jun 2008 | Member Level: Gold | Rating: Points: 2 |
Answer of Question 1:
Angle = 6M -(30H+M/2)
where M=minute and H=hour.
if you get a negative angle it simply means that the hour hand is ahead of th minute hand.

==> (360/12)Hours from 0:00 - (360/60)*Minutes from 0:00.
Hope it is clear.

2.My age : 10x+y
Son age : 10y+x
so 10x+y = 10y+x
10x+y-1 = 2(10y+x-1)
x = (19y-1)/8
for y=3
(19y-1) is completely divisible by 8
so x = 7
So my present age : 10*7+3 = 73
son's age : 10*3+7 = 37

3.8
6561/3= (2187,2187,2187)
2187/3= (729, 729, 729)
till 1 we have to divide.
It will have 8 weighing till 1
