• 25. Simplify
  (31/10) * (3/10) + (7/5) / 20

  1. 0
  2. 1
  3. 10
  4. 100

  Answer :

  Option B

  Explanation:

  = (31/10) * (3/10) + (7/5) / 20
  = (3.1) * (.3) + (1.4) / 20
  = 0.93 + 0.07
  = 1

• 26. Value of
  \begin{aligned}
  \frac{1}{2+\frac{1}{2+\frac{1}{2-\frac{1}{2}}}}
  
  \end{aligned}

  1. \begin{aligned} \frac{6}{19} \end{aligned}
  2. \begin{aligned} \frac{7}{19} \end{aligned}
  3. \begin{aligned} \frac{8}{19} \end{aligned}
  4. \begin{aligned} \frac{9}{19} \end{aligned}

  Answer :

  Option C

  Explanation:

  \begin{aligned}
  = \frac{1}{2+\frac{1}{2+\frac{1}{\frac{3}{2}}}}
  \end{aligned}
  \begin{aligned}
  = \frac{1}{2+\frac{1}{2+\frac{2}{3}}}
  \end{aligned}
  
  \begin{aligned}
  = \frac{1}{2+\frac{1}{\frac{8}{3}}}
  \end{aligned}
  
  \begin{aligned}
  = \frac{1}{2+\frac{3}{8}}
  \end{aligned}
  
  \begin{aligned}
  = \frac{1}{\frac{19}{8}}
  \end{aligned}
  
  \begin{aligned}
  = \frac{8}{19}
  \end{aligned}

• 27. Simplify
  \begin{aligned}
  \frac{\frac{7}{2}\div {\frac{5}{2}} \times {\frac{3}{2}} }{\frac{7}{2} \div { \frac{5}{2}} of \frac{3}{2} } \div 5.25
  \end{aligned}

  1. \begin{aligned} \frac{3}{5} \end{aligned}
  2. \begin{aligned} \frac{3}{6} \end{aligned}
  3. \begin{aligned} \frac{3}{7} \end{aligned}
  4. \begin{aligned} \frac{3}{8} \end{aligned}

  Answer :

  Option C

  Explanation:

  \begin{aligned}
  \frac{\frac{7}{2}\div {\frac{5}{2}} \times {\frac{3}{2}} }{\frac{7}{2} \div { \frac{5}{2}} of \frac{3}{2} }\div 5.25
  \end{aligned}
  
  \begin{aligned}
  = \frac{\frac{7}{2}\times {\frac{2}{5}} \times {\frac{3}{2}} }{\frac{7}{2} \div { \frac{15}{4}}}\div 5.25
  \end{aligned}
  
  \begin{aligned}
  = \frac{\frac{21}{10}}
  {\frac{7}{2} \times { \frac{4}{15}}}\div {\frac{525}{100}}
  \end{aligned}
  
  \begin{aligned}
  = \frac{21}{10}\times{\frac{15}{14}}\times\frac{100}{525}
  
  = \frac{6}{14}
  = \frac{3}{7}
  \end{aligned}

• 28. Company workers decided to raise Rs. 3 lakhs by equal contribution from each. Had they contributed Rs. 50 each extra, the contribution would have been Rs. 3.25 lakhs. How many workers were they?
