B)
P Q R S 0.115 1.11 1.17 3.25
C)
P Q R S 0.15 1.1 1.7 2.5
D)
P Q R S 0.25 1.21 2.17 4.15
Correct Answer: C
Solution :
(i) We have, \[\sqrt[3]{0.003375}=\sqrt[3]{\frac{3375}{1000000}}\] \[=\frac{15}{100}=0.15\] (ii) We have, \[\sqrt[3]{1.331}=\sqrt[3]{\frac{1331}{1000}}=\frac{11}{10}=1.1\] (iii) We have, \[\sqrt[3]{4.913}=\sqrt[3]{\frac{4913}{1000}}=\frac{17}{10}=1.7\] (iv) We have,\[\sqrt[3]{15.625}=\sqrt[3]{\frac{15625}{1000}}=\frac{25}{10}=2.5\]
