the age of mother is three times that of the elder son . after ten year the age of mother will be four times that of the younger son . if different in age of the two sons is 15 year what is the age of the mother
Answers
Answer:
Let the age of mother be x years, the age of elder son be y years
be x years, the age of elder son be y years and the age of younger son be z years.
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we have
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we havex=2y ...(i)
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we havex=2y ...(i)From the second condition, we have
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we havex=2y ...(i)From the second condition, we havex+10=3(z+10)
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we havex=2y ...(i)From the second condition, we havex+10=3(z+10)∴x+10=3z+30
be x years, the age of elder son be y years and the age of younger son be z years.From the first condition, we havex=2y ...(i)From the second condition, we havex+10=3(z+10)∴x+10=3z+30∴x−3z=20 ...(ii)
