Read Solution (Total 5)
-
- let Present ages of sun = x and manorama = 6x
after 7 years 6x+7 and x+7 in the ration 11 : 3
6x+7 11
------- = ----
x + 7 3
:- 3(18x+7) = 11(x+7)
= > 7x = 56
:- x = 8
Present age of manorama is 6x = 6*8 = 48 years - 8 years agoHelpfull: Yes(7) No(0)
- let the age of the son be=x yrs.....so manoramas age will be=6x yrs.
after seven years the ratio will be:- 6x+7/x+7=11/3.... so,x=8 yrs..so the present age of the son is 8yrs..so manoramas age will be=6x=48yrs..
- 8 years agoHelpfull: Yes(0) No(0)
- 6x+7/x+7=11/3
x=8
6*8=48 - 8 years agoHelpfull: Yes(0) No(0)
- 5) 48 years
son's age 8 years - 8 years agoHelpfull: Yes(0) No(0)
- At present,let m=Manorama
s=son
m=6s
after 7yrs,
(6s+7)/(s+7)=11/3
18s+21=11s+77
s=8
m's present age=6(8)=48yrs - 4 years agoHelpfull: Yes(0) No(0)
