The ratio of the price of a loaf of bread to the price of a packet of sugar in 1975 was r : t. In 1980, the price of a loaf went up by 25% and that of a packet of sugar went up by 10%. Their new ratio is now
Ratio of bread to sugar = r:t
25% increase in bread = \(\frac{125r}{100}\)
10% increase in sugar = \(\frac{100t}{100}\)
New ratio = \(\frac{125r}{100}\):\(\frac{110t}{100}\)
= 25r:22t
= 50r:44t
