  • question_answer Read the following statements carefully and choose the correct option. Value of \[\frac{0.216+0.064}{0.36+0.16-0.24}\] is 1. If \[4.175\,=\frac{1}{0.2395}\] then the value of \[\frac{1}{0.0004175}\] is equal to 2935. (iii) Value of [0.9 -{2.3 - 3.2 - (7.1 - 5. 4 -3.5)}] is 0.

    A) and (ii) are true while (iii) is false.

    B) and (iii) are true while (ii) is false.

    C) (ii) and (iii) are true while (i) is false.

    D) All the given (i), (ii) and (iii) are true.

    Correct Answer: B

    Solution :

    (i) \[\frac{0.216+0.064}{0.36+0.16-0.24}=\frac{0.28}{0.28}=1\] (ii) \[\frac{1}{0.0004175}\,=\frac{10000}{4.175}\] \[=10,000\times 0.2395\] = 2395 (iii) Given expression is equal to \[[0.9-\{2.3\,-3.2-(7.1-8.9)]\] \[=[0.9-\{2.3-3.2+1.8\}]\] \[=[0.9-\{4.1-3.2\}]\] \[=[0.9\,-0.9]=0\] Figure Based MCQ
