half of one number is one third of another .the sum of the two numbers is 95.what are the two numbers ?
Answers
- we need to find the two numbers.
- Half of one number is one third of another
- sum of the two numbers is 95
Let the two numbers be x and y.
- Sum of two numbers is 95
↛ x + y = 95
↛ x = 95 - y ⠀⠀⠀......1)
- Half of one number is one third of another.
↛x × ½ = ⅓ × y
- From equation⠀⠀⠀...1)
↛ (95 - y)/2 = y/3
↛ 3(95 - y) = 2 × y
↛ 285 - 3y = 2y
↛ - 3y - 2y = -285
↛ -5y = -285
⪼ y = 285/5
⪼ y = 57
- Substituting value of y in ⠀⠀...1)
⇝x = 95 - y
⇝ x = 95 - 57
⇝ x = 38
Hence,
- Two numbers are 38 and 57
- Sum of two numbers is 95
↛ x + y = 95
↛ 38 + 57 = 95
↛ 95 = 95
LHS = RHS
Hence , verified.

✴ Half of one number is one third of another .the sum of the two numbers is 95.what are the two numbers ?
↗ The two numbers are 57 & 38.
Given :-
- Half of one number is one third of another .
- The sum of the two numbers is 95.
To Find :-
- The two numbers .
Calculation :-
Let the no. be x & y.
According to the question,
- The half of one number is one third of another.
➡ 1/2x = 1/3y
➡ x = 1/3y × 2/1
➡ x = 2/3 y..............(1)
- The sum of the two numbers is 95.
➡ x + y = 95....................(2)
Putting equation (1) in (2)
➡ x + y = 95
➡ 2/3y + y = 95
➡ 2y + 3y / 3= 95
➡ 5y/3 = 95
➡ 5y = 95 × 3
➡ 5y = 285
➡ y = 285/5
➡ y = 57
Putting value of y in equation 2.
▶ x + y = 95
➡ x + 57 =95
➡ x = 95 -57
➡ x = 38
Hence ,The two numbers are 57 & 38.
_____________________________________
1/2x = 1/3y. [Given]
➡ 1/2 × 38 = 1/3 × 57
➡ 19 = 19
Hence, L.H.S = R. H. S.
