since, 1 yr is equal to 365 or 360 days. Using 365 days a year, then their is 52.1428 weeks per year...The problem must state a condition, using 1 year is equal 52 weeks.

ReplyDeleteGardan 6 years father 72 son 42 years old

ReplyDeleteI have question regarding this statement "My grandson is about as many days as my son in weeks"

ReplyDeleteIf the answer is grandpa = 72 years old, son = 42 years, grandson = 6 years,

then :

grandson = 6 years, then in days = 6*365 = 2190

son = 42 years = then in weeks = 42 * 52 = 2184

2190 <> 2184, so the son's age is not exactly 42 year old ?

its the grandson's age when compared to the son's age is about as many days as a week.

Deletelike 1:7

The ages are approximations

ReplyDeleteGiven:

ReplyDeleteS = d (days)

D = w = d (same as number of days)

G = y = d/30 (days/30 = months)

Deducted:

S (in years) = d/365

D (in years) = d/52

G (in years) = d/30

So:

d/365 + d/52 + d/30 = 120

d(1/365 + 1/52 + 1/30) = 120

d(.0027 + .0192 + .0333) = 120

d(.0552) = 120

d = 120/.0552 = 2174

Therefore, in years:

S = 2174/365 = 5.9562 ≈ 6

D = 2174/52 = 41.8077 ≈ 42

G = 2174/30 = 72.4667 ≈ 72

6 + 42 + 72 = 120

Grandfather is 72.
