तो बताओ कौन कितने कितने साल का

Answer 1

let grandson is x yrs old=12x months=12x*30 days=360x days
The grandfather's age is equal to the number of months of the grandson
so age of grandfather=12x yrs
The father's age in weeks is equivalent to the grandsons age in days
so father's age in weeks=360x
so father's age in yrs=360x/52=90x/13
The 3 together are 140 years old
so x+12x+90x/13=140

or 13x+156x+90x=140*13=1820
or 259x=1820
or x=7.02=7 yrs
so age of grandfather=12x yrs=12*7=84 yrs
so father's age in yrs=360x/52=90x/13=90*7/13=48.46=49 yrs
the individual ages of the 3 are 7,49,84
we have taken 1 yr=12 months
1 month =30 days
1yr=52weeks

f = 49, g = 84, s = 7
