SSC CGL 20191)The value of \({7+8 \times8 \div8 of 8+8\div8\times4 of 4}\over{4\div4 of 4+4\times4\div4-4\div4 of 2}\) is :
Correct Option: D
6.4
\({7+8 \times8 \div8 of 8+8\div8\times4 of 4}\over{4\div4 of 4+4\times4\div4-4\div4 of 2}\);
On solving by the BODMAS rule,
\(7+{8\times8\over8\times8}+8\times{1\over8}\times16\over4\div16+4-4\times{1\over8}\) = \(7+1+16\over{1\over4}+4-{1\over2}\) = \(24\over{1+16-2\over4}\) = \(32\over5\) =6.4
