Question

the sum of 3 consecutive multiples of 5 is 945 find the largest multiply

Answer 1

Let the first multiple be 5a

Second multiple = 5a + 5

Third multiple = 5a + 10

According to question

5a + 5a + 5 + 5a+ 10 = 945

=> 15a + 15 = 945

=> 15a = 930

=> a = 62

First multiple = 62 × 5 = 310

Second multiple = 310 + 5 = 315

Third multiple = 310 + 10 = 320

Answer 2

HEY FRIEND

HERE IS YOUR ANSWER

Let the multiples be 5x, 5x+5,5x+10

ACCORDING TO QUESTION :

5x+(5x+5)+(5x+10)=945

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

15x+15=945

15(x+1)=945

x+1=945/15

x+1=63

x=62

================================

THE MULTIPLES ARE :

5x=5×62=310

5x+5=5×62+5=310+5=315

5x+10=5×62+10=310+10=320

================================

THE LARGEST MULTIPLE IS 320

================================

HOPE THIS HELPS YOU ☺
