Answers
question:
the ages of Rahul and laxmi are in ratio 5:7.four years later the sum of their ages will be 56 years what are their present ages?
solution:
rahul's age = 20 , laxmi's age = 28
To find:
what are their present ages?
Given:
the ages of Rahul and laxmi are in ratio 5:7.four years later the sum of their ages will be 56 years
step by step explanation:
let the ages of Rahul and laxmi be 5x and 7x
four year later:
rahul's age = (5x + 4) and laxmi's age = (7x + 4)
therefore:
rahul's age = 5 × 4 = 20 and laxmi's age = 7 × 4 = 28.
Present age of Rahul = 4 × 5 = 20.
Present age of Laxmi = 4 × 7 = 28.
- Let the present age of rahul be = 5x years.
- Let the present safe of laxmi be = 7x years.
Now , it is given that 4 years later their age will be 56 years.
So,
4 years later ,
Now , According to the question ,
we get
Hence ,
Present age of Rahul = 4 × 5 = 20.
Present age of Laxmi = 4 × 7 = 28.
