Answer 1

Answer:

Step-by-step explanation:

Let us assume x as grandson's age

y as Dad's age

z as grandfather's age

Case1

x+y+z=140 (given) -1

Case2

x/y=1/7 (ratio of days and weeks)

7x=y .........-2

Case3

x/z=1/12

(ratio of months and years)

12x=z...............-3

On substituting 2 and 3 in 1

x+7x+12x=140

20x=140

x=7 years

On substituting x=7 in 2 and 3

7(7)=y , 12(7)=z

y=49 years. , z= 84 years

I hope this helped

Thank you
