ప్రశ్న ప్రకారం,
⇒ S1 యొక్క ఉపరితల వైశాల్యం : S2 యొక్క ఉపరితల వైశాల్యం = 9 : 1
⇒ 4πR2 : 4πr2 = 9 : 1
⇒ R : r = 3 : 1
⇒ S1 యొక్క ఘనపరిమాణం : S2 యొక్క ఘనపరిమాణం = R3 : r3
⇒ S1 యొక్క ఘనపరిమాణం : S2 యొక్క ఘనపరిమాణం = 33 : 13
⇒ S1 యొక్క ఘనపరిమాణం : S2 యొక్క ఘనపరిమాణం = 27 : 1
S2 యొక్క ఘనపరిమాణం S1 కంటే తక్కువగా ఉన్న శాతం = x %
x% = [(27 -1)/27] x 100 = (26/27) x 100 ≈ 96.29%
∴ సరైన సమాధానం ఎంపిక (3).
