Vaishali wears a beautiful piece of clothing called a Saree, a traditional Indian dress for women. It is mostly tangerine-colored, with blue, brown, and gold-colored decorative stripes. There are three times as many gold stripes as brown stripes, and five times as many blue stripes as gold stripes. If there are 4 brown stripes, how many blue stripes does Vaishali's Saree have? Let's think first. Chain of thought:
With 3 times as many gold stripes as brown stripes, this means there are 3 * 4 = 12 gold stripes. With five times as many blue stripes as gold stripes, this means there are 5 * 12 = 60 blue stripes.
Therefore, the answer is 60.
