152

A) -343
B) -127
C) -75
D) 126

Answer 1

If I read your problem write: 126

Explanation:

if I interpret this as

- (-3)* 2 * (5) * 2 * (7) * 3 divided by 5 * 2

we can get 126

because:

- (-3)* 2 * (5) * 2 * (7) * 3 divided by 5 * 2

= 6 * 5 * 2 *7 * 3 / (5*2)

= 60*7 * 3/ (5*2)

= 420 * 3 / 10

= 1260/10

= 126
