Answer:
Given that :
Ram is twice as old as Shyam.
Five years ago his age was three times of Shyam's age.
To find:
Present age of Ram.
Present age of Shyam.
Solution:
Let the present age of Ram be x years
Let the present age of Shyam be y years.
As per second condition :-
Ram is twice as old as Shyam
Representing mathematically,
x = 2y ---> 1
As per second condition:-
five years ago his age was three times of Shyam's age.
Ages 5 years ago :-
Ram's age = x - 5 years
Shyam's age = y - 5 years
Representing the second condition mathematically,
x - 5 = 3 ( y - 5)
x - 5 = 3y - 15
x - 3y = - 15 + 5
x - 3y = - 10 -----> 2
Substitute value of x in equation 2,
2y - 3y = - 10
- y = - 10
y = 10
Substitute value of y in equation 1,
x = 2y ---> 1
x = 2 ( 10)
x = 20
•°• Present age of Ram = x = 20 years.
Present age of Shyam = y = 10 years
Ram is twice as old as Shyam
Present age of Ram = x = 20 years
Present age of Shyam = y = 10 years
=> x = 2y
=> 20 = 2 (10)
=> 20 = 20
LHS = RHS.
Five years ago his age was three times of Shyam's age
Ages 5 years ago :-
Ram's age = x - 5 = 20 - 5 = 15 years
Shyam's age = y - 5 = 10 - 5 = 5 years
=> x - 5 = 3 ( y - 5)
=> 15 = 3 ( 5 )
LHS = RHS.
Hence verified

a) Srilanka emerged as an independent country in 1948. Srilanka gained Independence from Bristish on 4th February, 1948.
b) Both the a and c were not the provisions of the act of 1956 passed in Sri Lanka.

Some important points realted to the Sri Lankan issue:
• After gaining Independence, Srilanka adopted Majoritarianism.
• According Majoritarianism, a particular ethnic group or linguistic group dominate the other groups.
• In Srilanka, the Sinhalese community dominated the Tamil community.
• The newly framed constitution increased the feeling of alienation.
• Thus, the Tamils in Srilanka demanded equal opportunities, to recognize Tamil as an official language, regional autonomy etc.
• This also led to the rise of civil war in Srilanka which led to killings of many innocent people.
