Let the ages of grandpa,his son and grandson be x,y,z respectively.
x+y+z=100 --(1)
52y=365z --(2)
12z=x --(3)
From (1),(2),(3) we've
12z+7z+z=100
20z=100
or,z=5
Hence x=60.

@KIRTI......
IF A can complete a work in 20 days and take rest at 4 days mean
1 2 3 4 _5 will be rest day
6 7 8 9 _10 rest
11 12 13 14 _15 rest
16 17 18 19 _20 rest day
mean he will complete the work in 24 days

now if we see B will complete the work 36 days like
1 2 3 4 _5 rest
6 7 8 9 _10rest
_15
_20
25
30 mean he can complete the work in 30 days but after taking rest 36 days
so
1/A+1/B=1/24+1/36
=3/36
=1/12
A+B=12 THEY AN COMPLETE THE WORK IN 12 DAYS
KIRTI NOW GOT OR NOT.........
