Answer: (d) Rs46.67 lacs

Solution: Let the expenditure of the company B in the year 2012 = Rs. X lacs

then, $$ \frac{5}{X} \times 100 = 12 $$ $$ X = \frac{5 \times 100}{12} $$ $$ X = 41.67 \ lacs $$ Hence, the income of the company B in the year 2012, $$ = (5 + 41.67) \ lacs $$ $$ = Rs46.67 \ lacs $$
