One year ago, the ratio of Roonie’s and Ronaldo’s age was 6: 7 respectively. Four years hence, this ratio would become 7: 8. How old is Ronaldo ?

• 7(x-1)=6(y-1)=> 7x-6y-1=0 ----eq1
  8(x+4)=7(y+4)=> 8x-7y+4=0 ----eq2
  on solving eq1 n eq2
  y=36

• Ans 28 years
  If the present age of Roonie=6x & Ronaldo=7x
  Then (6x+4)/(7x+4)=7/8 ->48x+32=49x+28 or x=4
  Therefore Ronaldo's age=7*4=28 years

• one year ago 6(x-1),7(x-1)
  after 4 years 6(x-1)+5,7(x-1)+5
  given ratio 7:8 after 4 years
  6(x-1)+5=7y
  6x-7y=1......1
  7(x-1)+5=8y
  7x-8y=2.....2
  from 1&2 u got x=6 then ronaldo age is=7x+1(because 7x means one year ago age ao u add 1)
  ans:36

• let 6x,7x are ages one year ego.so 6x+5/7x+5=7/8.by solving x=5.
  ronaldo age=7*5=35 but it is one year ago hence present age is 36.

• let one year ago roonie and ronaldo age be 6x and 7x respectively so according to question (6x+1)+4 /(7x+1)+4 =7/8 solving this we will get x=5, so ronaldo present age will be 7*5+1=36 :)

• one year ago the ages of roonie n ronaldo be 6x,7x
  now the ages are 6x+1,7x+1
  after 4 yrs ,the ages will be 6x+5,7x+5
  (6x+5)/(7x+5)=7/8
  x=5
  ronaldo age=6x+1=31

• ((6x+1)+4)/((7x+1)+4)=7/8
  (6x+5)8=(7x+5)7
  48x+40=49x+35
  x=5
  Sub x=5, 7(5)+5= 40
  Therefore, Ronaldo's age is 40

• one year ago their ages 6x:7x, now 6x+1:7x+1
  4 year hence, (6x+5)/(7x+5)= 7/8 so x=5
  Ronald's age now 7x+1= 36

• 6x+4/7x+4=7/8...=12..ronald is 7x=7*12=84 years
• 11 years agoHelpfull: Yes(0) No(17)
• lt 1 yr ago dr age 6x nd 5x now from prsnt age 4yrs hnce dr age will b 6x+1+4=6x+5
  & 7x+5 so, (6x+5)/(7x+5)=7/8 => 48x+40=49x+35 =>x=5 so ronld's prsnt age 7*5+1=36
