Answer: Given:– Ratio of ages of Suresh and his father=2:7 Difference=40 years Assumption:– Let the age of Suresh be 2x and his father be 7x According to question:– 7x-2x=40 5x=40 [tex]x = \frac{40}{5} [/tex] x=8 Age of Suresh=2x =2(8) =16 years Age of his father=7x =7(8) =56 years Therefore:– Age of Suresh before 6 years=16-6 =10 years Age of his father before 6 years=56-6 =50 years Ratio=10:50 = 1:5 Option 4) 1:5 is correct Reply
Answer:
Given:–
Ratio of ages of Suresh and his father=2:7
Difference=40 years
Assumption:–
Let the age of Suresh be 2x and his father be 7x
According to question:–
7x-2x=40
5x=40
[tex]x = \frac{40}{5} [/tex]
x=8
Age of Suresh=2x
=2(8)
=16 years
Age of his father=7x
=7(8)
=56 years
Therefore:–
Age of Suresh before 6 years=16-6
=10 years
Age of his father before 6 years=56-6
=50 years
Ratio=10:50
= 1:5
Option 4) 1:5 is correct
