Answer / guest
Let son's present age is X years.
Hence, father's present age is (3X + 3) years.
After 3 years, son's age will be (X + 3) years.
and father's age will be (3X + 6) years.
But given that after 3 years father's age will be ten years
more than twice the son's age.
(3X + 6) = 2 * (X + 3) + 10
3X + 6 = 2X + 16
X = 10
Therefore, father's present age is 33 years.

Answer / bhushan
No!!!! All the answres are wrong! Let me elaborate it
mathematically.
suppose fathers todays age: x years
Sons todays age : y years
by first relation : x= 3y+3...............(1)
by second relation : x+3= (y+3)*2+10
x+3= 2y+6+10=2y+16
x+3=2y+16
x=2y+13..............(2)
from (1) & (2)
y-10= 0
so, y=10 years.
so, sons age is 10 years
and fathers age is 33 years, which
satisfies both given condition

Answer / digumber thakur
LET THE SON'S PRESENT AGE BE x YEARS
FATHER'S PRESENT AGE IS (3x+3) YEARS
AFTER 3 YEARS, SON'S AGE WILL BE (x+3) YEARS
AND FATHER'S AGE WILL BE (3x+6) YEARS
GIVEN: AFTER 3 YEARS FATHER'S AGE WILL 10 YEARS MORE THAN
TWICE THE SON'S AGE.
(3x+6)=2(x+3)+10
3x+6=2x+16
x=10
THEREFORE,FATHER'S PRESENT AGE = 33 YEARS
AND, SON'S PRESENT AGE = 10 YEARS

Answer / parvati desai
father's age=3+3*son's age
after 3 years
father's age=10+2*son's age
if son is 10 now his father is 3+3*10=33 and after 3 years his father will be 36 and his son will be 13 therefore 36=10+2*13

Answer / kelley w.
Oh my gosh. It's really not that hard. Let me spell it out
for you...
Let's assume the father's current age is "f" and the son's
current age is "s".
f=3s+3 [Father's age is 3 times the Son's age
and 3 more years]
3+f=3+2s+10 [In 3 years, father's age will be twice
the son's age plus 10 more years]
3+(3s+3)=2s+13 [The Transitive Property of Equality
allows us to subsitute "3s+3" for "f"]
s=7 [By subtracting 6 and 2s from each
side, you are left with "s=7"]
therefore, f=24. [By plugging in "7" for "s" in our
original equation, we see that f=24.]
I don't understand why everyone is getting these ridiculous
answers, so I explained my answer in as much detail as I
deemed necessary. It's really not that hard guys.

Answer / rashmi
Let the father's present age be X years.
Let the son's present age be Y years.
Presently,
X = 3Y(according 2 the first part of the question)
---------(1)
After 3 years,
Father's age = X+3
Son's age = Y+3
given, X+3 = 10+2*(Y+3)----------------(2)
Thus, X - 2Y = 13(from 2)
X - 3Y = 0(from 1)
By solving, Y = 13
SO X = 39(present father's age)

Substitute digits for the letters to make the following subtraction problem true. S A N T A - C L A U S ----------------- X M A S Note that the leftmost letter can't be zero in any word. Also, there must be a one-to-one mapping between digits and letters. e.g. if you substitute 3 for the letter M, no other letter can be 3 and all other M in the puzzle must be 3.
