Question

The sum of two consecutive multiples of 5 is 55. Find these multiples.

Answer 1

Let the first multiple of 5 be x.

Then the other multiple of 5 will be x + 5 and their sum = 55

Therefore, x + x + 5 = 55

$\Rightarrow 2x+5=55$

$\Rightarrow 2x=55-5$

$\Rightarrow 2x=50$

$\Rightarrow x=\frac{50}{2}$

$\Rightarrow x=25$

Therefore, the decond multiples of 5, i.e., x + 5 = 25 + 5 = 30

Therefore, the two consecutive multiples of 5 whose sum is 55 are 25 and 30.
