Dear Frnds
Mostly a question always ask related AGE…….
So we discuss how solve Age related problem in minimum time with accuracy.
When Current Age Ratio Know Q.The Ratio of age of Ram And Manoj 2:1 after 5 years the age ratio become 3:2. Find Both current age.
Solution : First Under line for time(After /Before)
R. M
Current age. 2. 1
+5 years. 3. _ 2
Diff=1
Current age and +5 years ratio diff2=1(2-3)and (1-2)
Note: Here both difference Is equal 1.
5(time)×2(Ratio) *Diff1
Current age Ram= -——————
Diff2
Ram=5×2
=10years
Manoj=5×1
=5years
CASE 2: IF both Difference are not equal ….
Q2. If the ratio of father and son age 5:1 and after 3year the age ratio 4:1. Find current age of son.
Solution :
Son. Father
Current. 1. 5.
|Diff2=1
+3 years. 1. ____ 4
Diff1=3
Note : Here both difference are not same .
3(time)×1(Ratio)*3(Diff1)
Age of son. = -——————
1 ( Diff2)
3×1×3
= ——— =9
1
Current Age of Son =9 years (‘-‘)
