Answer»

? Cost of 150 ml tasty solution = Rs. 27

∴ Cost of 1 ml tasty solution = Rs. $(\frac{{27}}{{150}})$

∴ Cost of 1 litre of tasty solution = 1000 × (9/50) = Rs. 180

Cost of 1 kg of salt = Cost price of cheaper = c = Rs. 30

Cost of 1 litre of soup = Cost price of dearer = d = Rs. 183

Cost of 1 litre of tasty solution = MEAN price = m = Rs. 180

By formula,

$(\BEGIN{array}{l} \frac{{{\rm{Quantity\;of\;salt}}}}{{{\rm{Quantity\;of\;soup}}}} = \frac{{{\rm{Quantity\;of\;Cheaper}}}}{{{\rm{Quantity\;of\;Dearer}}}} = \frac{{{\rm{d}} - {\rm{m}}}}{{{\rm{m}} - {\rm{c}}}}\\ \Rightarrow \frac{{{\rm{Quantity\;of\;Salt}}}}{{{\rm{Quantity\;of\;Soup}}}} = \frac{{183 - 180}}{{180 - 30}} = \frac{3}{{150}} \end{array})$

∴ The required ratio = Salt ? Soup = 1 ? 50.
