  Answer :

  Option C

  Explanation:

  In 1997 for company A, we have
  let export be E and Import be I
  \begin{aligned}
  \frac{E}{I} = 1.75\\
  => E = 1.75I\\
  
  \text{New Imports }I_{new}=40\%&of;&I;\\
  = 1.4I \\
  
  \text{New ratio =}\frac{E}{I_{new}}\\
  = \frac{1.75I}{1.4I} \\
  = 1.25
  \end{aligned}

• 5. In 1995, the export of the company A was double that of company B. If the imports of Company A during the year was Rs 180 crores, what was the approximate amount of imports of Company B during that year ?

  4. 410 crores

  Answer :

  Option B

  Explanation:

  \begin{aligned}
  \text{In 1995 for Company A we have}\\
  \frac{E_A}{I_A}=1.75 & .....(i)\\
  
  \text{In 1995 for Company B we have}\\
  \frac{E_B}{I_B}=0.75 & .....(ii)\\
  
  \text{Also, we have} E_A = 2 E_B & .....(iii)\\
  I_A = 180 crores \\
  \text{from (i)}\\
  E_A = 180 * 1.75 = 315 crores \\
  
  \text{from (iii)}\\
  E_B = \frac{E_A}{2} = \frac{315}{2}crores \\
  
  \text{from (ii)}\\
  
  I_B = \frac{E_B}{0.75} \\
  = \frac{315}{2*0.75} \\
  = 210 crores
  \end{aligned}
