The product of abcde is negative.
(An odd number of digits are negative)
Given: a > b > c > d > e
a,b,c,d,e
+ + + + -
+ + - - -
- - - - -
1) e-a = -e-(a) = sum is negative. TRUE
2) d/c =
Either d/c or (-d/-c)
The negative sign gets cancelled. So, it’s always positive. FALSE
3) abe =
(a*b*-e) = -
(-a*-b*-e) = -
The multiplication of abe is always negative. TRUE
CORRECT ANSWER (E)
