Given:
Three consecutive integers are such that when they are taken in increasing order and multiplied by 2,3 and 4 respectively, they add up to 74.
To do:
We have to find the numbers.
Solution:
Let the three consecutive integers be $x, x+1$ and $x+2$
According to the given question,
$2\times x+ 3\times(x+1) + 4\times(x+2) = 74$
$2x + 3x + 3 + 4x + 8 = 74$
$9x+11=74$
$9x = 74-11$
$9x = 63$
$x = \frac{63}{9}$
$x = 7$
$\Rightarrow x+1=7+1=8$
$x+2 = 7+2 = 9$
Therefore, the required numbers are $7, 8$ and $9$.
