Answer 1

$»aNsWeR:-$

Let the no.s be => x , x+5 , x+10 , x+15 , x+20 , x+25

Total Sum of Multiples => 765

Now,

$x + x+5 + x+10 + x+15 + x+20 + x+25 = 765 \\ \\ = 6x + 75 = 765 \\ \\ 6x = 765 - 75 \\ \\ 6x = 690 \\ \\ x = \frac{690}{6} \\ \\ x = 115 \\ \\ ... \\ \\ x+5 = 115 + 5 = 120 \\ \\ x + 10 = 115 + 10 = 125 \\ \\ x + 15 = 115 + 15 = 130 \\ \\ x + 20 = 115 + 20 = 135 \\ \\ x + 25 = 115 + 25 = 140 \\ \\ so \: . \: \: largest \: no. \: \: is \: \: 140$
