If −7 ≤ x ≤ 5 and −15 ≤ y ≤ 0, then what is the greatest possible value of xy ?

A. -105
B. -75
C. 0
D. 75
E. 105


−7 ≤ x ≤ 5 and −15 ≤ y ≤ 0

CONCEPT: For maximum Value the sign of the result must be kept positive (if possible i.e. both x and y must have same sign
and their absolute values must be maximum


i.e. \(x*y_{max} = (-7)*(-15) = 105\)



Answer: Option E

IMO E

We have been asked to find the greatest possible integer,
Start off by checking if we can get positive integer by multiplying two numbers. And yes we can get a positive value by multiplying two negative values.
So focusing on getting the maximum positive value which we can get by multiplying two most negative no.
Hence 105.

Greatest value among the given values is 105, if i can get a value for xy, i will be good

-7 * -15

E
