As we know,
" ( ) " means multiplication.
Quantity A :
(- 8) (6) (4) (-9) (-12)
= (- 48) (4) (-9) (-12)
= (- 192) (-9) (-12)
= (1728) (-12) {Product of two "-" gives a "+" }.
= (-20736)
Quantity B :
(6) (-4) (6) (2) (-4)
= (-24) (6) (2) (-4)
= (-144) (2) (-4)
= (-288) (-4)
= 1152.
Clearly,
1152 > (-20736).
Quantity B > Quantity A
Hence, the correct answer is "Quantity B is bigger".
