Let the larger number be x and the smaller number be y. Then, we have:
x –y = 26 ………….(i)
x = 3y …………(ii)
On substituting x = 3y in (i), we get:
3y –y = 26
⇒ 2y = 26
⇒ y = 13
On substituting y = 13 in (i), we get:
x – 13 = 26
⇒ x = 26 + 13 = 39
Hence, the required numbers are 39 and 13.
Let the numbers are x and y.
Given that one number (let x) is three times the other (y).
i.e., x = 3y ⇒ x – 3y = 0. ... (1)
Given that the difference between both numbers is 26.
i.e., x – y = 26. ... (2)
Now subtracting equation (2) from equation (1), we get,
(x – 3y) – (x – y) = 0 – 26
⇒ – 2y = – 26 ⇒ y = \(\frac{26}{2}\)= 13.
Now putting the value of y = 13, in equation (2),
we get x – 13 = 26
⇒ x = 26 + 13 = 39.
Hence, the required number are 13 and 39.
Let the bigger number is x and smaller number is y.
Given that difference between both numbers is 26.
∴ x – y = 26. … (1)
Given that one number is three times the other
Therefore, x = 3y. … (2)
Now, putting x = 3y in equation (1), we get 3y – y = 26
⇒ 2y = 26 ⇒ y = \(\frac{26}{2}\) = 13.
Now, putting y = 13 in equation (2), we get
x = 3 × 13 = 39.
Hence, the numbers are 13 and 39.
Let the larger number be x and the smaller number be y.
Then, we have:
x –y = 26 ………….(i)
x = 3y …………(ii)
On substituting x = 3y in (i), we get:
3y –y = 26 ⇒ 2y = 26 ⇒ y = 13
On substituting y = 13 in (i), we get:
x – 13 = 26 ⇒ x = 26 + 13 = 39
Hence, the required numbers are 39 and 13.
