Read Solution (Total 3)
-
- present ages of reshma and ruchi be
9x 4x
ruchi's age After five years from hence be 4x+5
given differece aftr 5yrs is 5
so 9x-(4x+5)=5 ==> 5x=10
x=2
Sum of their present ages is 18+8=26
18-(8+5)=5
ans=26 - 11 years agoHelpfull: Yes(17) No(7)
- present ages of reshma and ruchi be
9x 4x
After five years from hence 9x+5 4x+5
given differece aftr 5yrs is 5
so 9x+5-4x-5=5
=>x=1
Sum of their present ages is 9+4=13 - 12 years agoHelpfull: Yes(10) No(12)
