In three more years, Miguel's grandfather will be six times as old as Miguel was last year.When Miguel's present age is added to his grandfather's present age,the total is 68.How old is each one now?

Well, Tom is 3 x 5 = 15 yrs now. Sam has 15 yrs to go to 20. Then Tom will be 15 + 5 = 30 yrs.

Or, Tom is 10 yrs older than Sam now, so when Sam is 20........

What can one say? Old age touches everybody and with old age problems start and we are always surprised. On PC's the beeps may signal a memory error.

Do you want the mean age of the four students? It's 16.5 .

These letters are used as a way to rate the quality and condition of the brandy.

Let Adjoa's age be x and Kwame's y.

• Adjoa is 3 years older than Kwame: x=y+3
• Seven years ago sum of their ages was 13: (x-7)+(y-7)=13
• Now you substitute first equation into second equation: (y+3-7)+(y-7)=13
• 2y-4-7=13
• 2y=24
• y=24/2=12 years
• x=y+3=12+3=15 years
• sum of their present ages is x+y=12+15=27 years

Correction: Bob is thrice as old as Peter.
Let b be the current age of Bob, and p the current age of Peter. Now, b=3p
Six years earlier the relations was: b-6=4*(p-6)=4p-24.
Take the 6 to the right side leaving b=4p-18
Remember that now b=3p. Use it in the equation above
b=(3p)=4p-18, This becomes 3p=4p-18 or 0=p-18, and p=18
Peter is 18 years old, and Bob is 3*18=54 years old.
Verification: 6 years ago Peter was 12 years old and Bob 48 years old. 48/12=4.

Jack = x years old
Alfred = x+22 years old

when jack is x+22 he will be = 3 times x

so find x

22 = 3x- x
22 = 2x
11 = x

jack = 11
so Alfred = jack + 22
Alfred = 33

note: if this is your home work its not cool to have someone else do for you.

The average age of a three year old starter would be, well, three years old.
But, if you're actually asking how long it should last, probably at least 10 years, with no unusual abuse and average mileage driven. There are lots of factors that can shorten the life span of any electrical component, with water being the main culprit.

Hahahaha, Aaala! Kafi sochna para, is tarha ho ga mere khyaal se;
140 Saal teenoN ki mila k banti hay;

Pota: 7Years
Baap: 49Years
Dada: 84Years

7+49+84 = 140 (Theek)

Pota kitnay Month ka = 7 x 12 = 84 => Dada ki umer in years (Theek)

Pota kitnay Din ka = 7 x 365 = 2555din => Baap ki umer in weeks [ (49x365) / 7 ] = 2555 (Ye be Theek)
