Ravi's mother’s present age is six times Ravi's present age. Ravi's age 5 years from now will be one third of his mother’s present age. What are their present ages?
Answers
Answer:
Sum of Ravi and his mother ages after 7 years = 49 years or 37 1/3 Years
Step-by-step explanation:
Let Say Ravi Present Age = R
Ravi Mother Present Age = 6R
after 5 years age of ravi will be one third of his mother's age ( Present age)
=> ( R + 5) = 6R/3
=> 3R + 15 = 6R
=> 3R = 15
=> R = 5
Ravi Present Age = 5 Year
Mother Present Age = 30 Years
after 7 Years
Ravi age = 12 Years
Mother Age = 37 years
Total Age = 12 + 37 = 49 Years
after 5 years age of ravi will be one third of his mother's age ( age after 5 years)
( R + 5) = (6R+ 5)/3
=> 3R + 15 = 6 R + 5
=> 3R = 10
=> R =10/3
Ravi Age = 10/3
Mother = 20 Years
after 7 Years
Ravi age = 10/3 + 7 = 31/3 Years
Mother Age = 20+ 7 = 27 years
Total Age = 31/3 + 27 = 112/3 = 37 1/3 Years

Answer:
Sum of Ravi and his mother ages after 7 years = 49 years or 37 1/3 Years
Step-by-step explanation:
Let Say Ravi Present Age = R
Ravi Mother Present Age = 6R
after 5 years age of ravi will be one third of his mother's age ( Present age)
=> ( R + 5) = 6R/3
=> 3R + 15 = 6R
=> 3R = 15
=> R = 5
Ravi Present Age = 5 Year
Mother Present Age = 30 Years
after 7 Years
Ravi age = 12 Years
Mother Age = 37 years
Total Age = 12 + 37 = 49 Years
after 5 years age of ravi will be one third of his mother's age ( age after 5 years)
( R + 5) = (6R+ 5)/3
=> 3R + 15 = 6 R + 5
=> 3R = 10
=> R =10/3
Ravi Age = 10/3
Mother = 20 Years
after 7 Years
Ravi age = 10/3 + 7 = 31/3 Years
Mother Age = 20+ 7 = 27 years
Total Age = 31/3 + 27 = 112/3 = 37 1/3 Years
