The total of the ages sai,kiran and ravi is 93 years .ten
years ago the tatio of their ages was 2:3:4 what is the
percentage of ravi...(*** plz give explanation***)

Answer Posted / saurabh

let us assume there age at present as "x"

therefore the equation would be :=

(2x-10)+(3x-10)+(4x-10)=93

solving it

9x-30=93

or

9x=93-30

or

9x=63

i.e
x=63/9

x=7

there present age is.......
sai=2(7)+10 == 24
kiran=3(7)+10 ==31
ravi=4(7)+10 ==38

Is This Answer Correct ?    10 Yes 4 No
