Sachin is younger than Rahul by 7 years If the ratio of their ages is 7 9 find the age

Let age of sachin be x yrs.
Then age of rahul be x + 7 yrs.
Now,
7(x + 7) = 9x
7x + 49 = 9x
2x = 49
x = 24.5
So, age of sachin is 24.5 yrs.

b> 24.5
suppose sachin age is 7x & rahul age is 9x.den a/c to ques:
9x-7x=7
x=3.5
hence,sachin's age is:7x=7*3.5=24.5

Let the common factor is x
ratio= 7:9
then, Sachin= 7x and rahul= 9x
Sachin is younger than Rahul by 7 years
9x = 7x+7
2x = 7
x = 7/2
Sachin's age is = 7* (7/2)
= 49/2
=24.5 (ans)

its 24.5 as per equations

Let Sachin age=x
Rahul age=y
A/C ?
x=9y-7
x:y=7:9
so y=9x/7
replace and get answer=24.5

s+7=r .....(1)
s/r=7/9 ...(2)
on solving both equ.
we get s=24.5

let rahul age be x yrs
Given : Sachin is younger than rahul by 7 yrs
So, sachin's age=(x-7) yrs

x-7/x=7/9(given in qn)

x=31.5
Sachin age= (31.5-7)=24.5
ANS:b)24.5
10 years agoHelpfull: Yes(0) No(0)
ans : 24.5
10 years agoHelpfull: Yes(0) No(1)
let sachin age=x=rahul age=x-7,
x/x-7=7/9
x=24.5
10 years agoHelpfull: Yes(0) No(1)
let the age of rahul be x
age of sachin = x-7
by question
x-7/x=7/9
9x-63=7x
x=31.5
sachin age = 31.5-7=24.5 yrs
so ans is b)
10 years agoHelpfull: Yes(0) No(0)
7/9=x/(x+7)
x=49/2
=24.5
