Answer 1

Answer:

34 years

Step-by-step explanation:

Ten years ago father was 12 times as old as his son at that time

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)⇒2x+40=12x+20

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)⇒2x+40=12x+20⇒10x=20

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)⇒2x+40=12x+20⇒10x=20 ⇒x=2

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)⇒2x+40=12x+20⇒10x=20 ⇒x=2 ⇒ age of son at present=x+10=2+10=12

Ten years ago father was 12 times as old as his son at that timeLet the age of the son before 10 years =x and age of the father before 10 years =12x10 years hence he will be twice as old as his son.2(x+10+10)=(12x+10+10)⇒2x+40=12x+20⇒10x=20 ⇒x=2 ⇒ age of son at present=x+10=2+10=12Age of the father at present=12x+10=122+10=34
