Answer 1

Answer:

Q.1

$-30+(-23)+10+(-65)+(-13)\\=-30-23+10-65-13\\=-30-23-65-13+10\\=-53-78+10\\=-131+10\\=-121\\=(-121)$

Q.2

$p-(-7)=-1 \ \ \ \ \ OR \ \ \ \ \ (-7)-p=-1\\p+7=-1 \ \ \ \ \ \ \ \ \ OR \ \ \ \ \ -7-p=-1\\p=-1-7 \ \ \ \ \ \ \ \ \ OR \ \ \ \ \ -7=-1+p\\p=-8 \ \ \ \ \ \ \ \ \ \ \ \ \ \ OR \ \ \ \ \ p=-7+1=(-6)$

Thus p = (-8)    or    p = (-6)

$p+6 \ \ \ \ \ \ \ \ \ \ \ \ \ OR \ \ \ \ \ p + 6 \\=(-8)+6 \ \ \ \ \ OR \ \ \ \ \ =(-6)+6\\=(-2)\ \ \ \ \ \ \ \ \ \ OR \ \ \ \ \ =0[which \ is \ not \ possible \ as \\. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ it \ is \ not \ given \ in \ options]$

Thus Value of p + 6 = (-2)
