Question 120

What's the Error? A clothing store charges ₹ 1024 for 4 T-shirts. A student says that the unit price is ₹ 25.6 per T-shirt. What is the error? What is the correct unit price?

Answer 1

By unitary method,
Cost of 4 T-shirts = ₹ 1024
Cost of 1 T-shirt = $\frac{1024}{4}$ = ₹ 256
So, the error = ₹ (256 - 25.6) = ₹ 230.4
Hence, the correct unit price is ₹ 256.
