Answer 2

Step-by-step explanation:

in the given options all of them positive and when we add them then we get 190

so, we neeed to check the sum of their cubes

(a) (100,90)

100^3+90^3=1000000+729000=1729000

(b)(95,95)

95^3+95^3=857,375+857,375=1,714,750

(c)(155,35)

155^3+35^3=3,723,875+42875=3,766,750

(d)(130,60)

130^3+60^3=2197000+216000=2,413,000

according all 1,714,750 is least so answer is (95,95)

option b
