shopper


A woman goes into a supermarket and buys four items.

Using a calculator she multiplies the cost (in pounds) instead of adding them.

At the checkout she says, "So that's £7.11" and the checkout man, correctly adding the items, agrees.

What were the prices of the four items?

This problem is taken from "Sums for Smart Kids" by Laurie Buxton, published by BEAM Education
