Question

The sum of three consecutive multipes of 5 is 945.find the largest multiple

Answer 1

Let the three consecutive multiple of 5 is:-

5x , 5x+5, 5x+10

According to question:-

5x + 5x+5 + 5x+10 = 945

15x+15 = 945

15x = 945 - 15

15x = 930

x = 930/15

x = 62

So the numbers are:-

5x = 5(62)
= 310,

5x + 5
= 310+5
= 315

&

5x+10
= 310+10
= 320

Hope it helps.
