• A. Rs 21.15 lakhs
• B. Rs 20.70 lakhs
• C. Rs 18.70 lakhs
• D. Rs 20.15 lakhs
• E. None of these

Answer 1

The correct option is B Rs 20.70 lakhs

Investment by company A,
$=\frac{2}{3}\times 27$
=Rs 18 lakh
Investment by company B,
=9 lakh
$\therefore$ For company A,
$75=\frac{P}{18}\times 100$
$\Rightarrow P=\frac{75\times 18}{100}=Rs13.5lakh$
$\therefore$ For company B,
$80=\frac{Q}{9}\times 100$
$\Rightarrow Q=Rs.\frac{80\times 9}{100}$lakh
=Rs 7.2 lakh
$\therefore$ Total profit earned,
=13.5+7.2
=Rs 20.7 lakh
