Type and Age Short
trick 1:-
|
|
If the ratio
of age of A and B is X:Y and sum of their age is T, then:-
|
|
1
|
Age of A ={X / (X+Y)}x T
years
|
2
|
Age of B ={Y / (X+Y)}x T
years
|
3
|
Difference between age of A
and B = {(X-Y) / (X+Y)}x T years , [If X > Y]
|
Example:- The ratio of age of Ajay and Vijay is 3:4. If sum of there age is 84 years, then find the age of Ajay.

Q1
|
Rajeev’s age after 16 years
will be 5 times his age 5 years back, What is the present age of
Rajeev?
राजीव की उम्र 5 गुना हो
जाएगी 16 वर्ष बाद उसकी 5 साल पूर्व
की उम्र के; उसकी वर्तमान उम्र क्या होगी।
|
ANS:
|
Let Rajeev’s present age be x
years. Then,
Rajeev’s age after 15 years = (x + 15) years.
Rajeev’s age 5 years back = (x — 5) years.
x + 15 = 5 (x — 5)
x + 15 — 5x — 25
4x = 40 _ x 10.
Hence,
Rajeev’s present age 10 years.
|
Q2
|
The ages of two persons
differ by 16 years. If 6 years ago, the eider one be
3 times as old as the younger one, find their present ages.
यदि दो आदमियो की उम्र का अंतर 16 साल हे ; यदि 6 साल पेहले
बड़े आदमी की उम्र 3 गुना हो
छोटे की उम्र के| तो दोनों की वर्तमान उम्र क्या होगी
|
ANS:
|
Let. the age of the younger
person be x years.
Then. age of the elder person = (x + 16) years.
3 (x — 6) = (x + 16 — 6)
3x — 18 x + 10
2x = 28
x = 14.
Hence
their present ages are 14 years and 30 years.
|
Q3
|
Rohit was 4 times as old as
his son 8 years ago. After 8 years; Rohit will be
twice as old as his son. What are their present ages?
8 साल पहले रोहित की उम्र 4 गुना थी
उसके पुत्र से | 8 साल पश्चात रोहित की उम्र 2 गुना होगी
उसके पुत्र से | उसकी वर्तमान उम्र क्या हओगी।
|
ANS:
|
Let son’s age 8 years ago be
x years. Then, Rohit’s age 8 years ago = 4x years.
Son’s age after 8 years = (x + 8) + 8 = (x + 16) years.
Rohit’s age after 8 years. = (4x + 8) + 8 = (4x + 16) years.
2 (x + 16) = 4x + 16
2x = 16
x =8
Hence, son’s present age
= (x + 8) = 16 years,
Rohit’s
present age
= (4x + 8) = 40 years.

Q4
|
One year ago, the ratio of
Gaurav and Sachin age was 6: 7 respectively
Four years hence, this ratio would become 7: 8. How old is Sachin
?
1 साल पहले गौरव और सचिन की उम्र का अनुपात 6:7 हे। 4 वर्ष पश्चात
उनका अनुपात 7:8 हो जाएगा | सचिन कितना
बड़ा हे
|
ANS:
|
Let Gaurav’s and Sachin’s
ages one year ago be 6x and 7x years respectively Then.
Gaurav’s age 4 years hence =(6x + 1)+ 4 => (6x + 5) years
Sechin’i, age 4 years hence = (7x + 1)+ 4 => (7x + 5) years.
=>(6x+5)/(7x+5) = 7/8
= 8(6x+5) = 7(7x+5) = 48x+40=49x+35 =
x =5
Hence, Sachin’s present age =
(7x + 1) = 36 years.

Q5
|
Abhay’s age after six years
will be three-seventh of his father’s age. Ten years
ago, the ratio of their ages was 1 : 5. What is Abbay, father’s
age at present?
6 साल बाद अभय की उम्र उसके पिता की उम्र के 3/7 रेह जाएगी। 10 साल बाद् उनकी
उम्र का अनुपात 1:5 हे | अभय के पिता
की वर्तमान उम्र क्या होगी।
|
Ans
|
Let the ages of Abbay and his
father 10 years ago be x and 5x years respectively. Then,
Abhay’s age after 6 years = (x + 10) + 6 = (x + 16) years.
Father’s age after 6 years = (5x + 10) + 6 = (5x + 16) years.
(x+16) = 3/7 (5x+l6)
= 7(x+16)=3(5x+16)
=7x+112=l5x+48
= 8x=64
x =8
Hence Abhay Father present age = 5x+10 = 50 Years

Type and Age Short
trick 2:-
|
|
If the ratio
of age of A and B is X:Y and difference between their age is T (there
X>Y), then:-
|
|
1
|
Age of A = {X / (X-Y)}x T years
|
2
|
Age of B = {Y / (X-Y)}x T years
|
3
|
Sum of age of A and B = {(X+Y) / (X-Y)}x T years
|
Example:- The ratio of present age of Ram and Shyam is 3:2. After 4 years Ram is elder then Shyam by 6 years, find the present age of Shyam.

trick 3:-
|
|
The ratio of present
age of
A and B = X:Y then:-
|
|
1
|
If before n years ratio of their
age is A:B, then
(X-n) / (Y-n) = A/B
|
2
|
If after n years ratio of their
age is P:Q, then
(X+m) / (Y+m) = P/Q
|
Example:- Before 10 years age of A is half of B. If ratio of there present age is 3:4, then what will be the sum of there age presently ?
Type and Age Short
trick 4:-
|
|
n years before, ratio
of age of A and B is X:Y then :-
|
|
1
|
If ratio of their age is
presently A:B, then
(X+n) / (Y+n) = A/B
|
2
|
If after m years, ratio of their
age is P:Q, then
(X+n+m) / (Y+n+m) = P/Q
|
Example:- Before 10 years age of A is half of B. If ratio of there present age is 3:4, then what will be the sum of there age after 10 years ?

trick 5:-
|
|
If
before n years, ratio of age of A,B and C is X:Y:Z, then ratio of their present age
|
|
1
|
=
(X+n) : (Y+n) : (Z+n)
|
Example:- Sum of present age of A , B and C is 90 years. Before 6 years the ratio of there age is 1:2:3. find the present age of C.
Type and Age Short
trick 6:-
|
|
If after m years ratio of age of A and B is
X:Y, then ratio of their present age
|
|
1
|
= (X-m)
: (Y-m)
|
Example:- Sum of present age of Rajesh and Shankar is 60 years. after 6 years ratio of Rajesh and Shankar is 7:5. find the age of Shankar.
Type and Age Short
trick 7:-
|
|
If A
is such smaller then B such that C is bigger, then
