To Solve:
- Find the original numbers
Given:
- A number is 4 times another number.
- When 12 is added to both the numbers, the first new number is 2 1/2 times the other new number.
Solⁿ:
- Assume the no.s
- Make eqⁿ according to question.
- Put them equal, find the values
- Put the values in the assumed no.s, and get the Original numbers.
» Let one number be = x
» Let another number be = 4x
When 12 is added:-
» 1ˢᵗ number = 12+x
» 2ⁿᵈ number = 12 + 4x
When Added:-
12 + 4x = 2 1/2 (12+x)
Solve:
Now, the numbers are :-
X = 12
4x = 4×12 = 48
So, the numbers are 12 and 48
