By mixing two brands of tea and selling the mixture at the rate of $₹177$ per $\mathrm{kg},$ a shopkeeper makes a profit of $18\%.$ If in every $2 \mathrm{kg}$ of one brand costing $₹ 200$ per $\mathrm{kg}, 3 \mathrm{kg}$ of the other brand, is added, then how much per $\mathrm{kg}$ does the other brand cost?

What amounts (in litres) of $90\%$ and $97\%$ pure acid solutions are mixed to obtain $21$ litres of $95\%$ pure acid solution?

Ratio of syrup and water in a sweet drink contained in bottle is $7:5.$ What part of the drink is to be taken out and replaced by water so that in the new mixture, syrup and water are in equal proportion?

A mixture of certain quantity of milk with $16 \mathrm{L}$ of water is worth $90$ paise per liter. If pure milk costs $108$ paise per liter, then the amount of milk in the mixture is:

The ratio in which a $30\%$ alcohol solution should be mixed with another $50\%$ solution in order to get a $42\%$ solution is:
