Question

If the sum of square of three consecutive multiples of 5 is 1250. Find these numbers​

Answer 1

Let the three consecutive multiples of 5 be 5x, 5x + 5 and 5x + 10The sum of three consecutiv

Answer 2

Let the 3 consecutive multiple of 5 are :

➝ 5x

➝ 5x + 10

➝ 5x + 15

The sum of three consecutive multiple numbers is 1250.

Now lets solve this ,

➝ 5x + 5x + 10 + 5x + 15 = 1250

➝ 15x + 25 = 1250

➝ 15x = 1250 - 25

➝ 15x = 1225

➝ x = 1225/15

➝ x = 81.6

Now as we found X so let's just put the values !

➝ 5x = 5×81.6 = 408

➝ 5x + 10 = 5×81.6 +10 = 418

➝ 5x + 15 = 5×81.6 + 15 = 423

So, The 3 consecutive multiple numbers are :

408,418,423
