The price of a washing machine in a shop on Miller Road is the same as the price of an identical washing machine in a shop on Washington Road.

Both the shops offered a discount on the washing machine during Christmas.

As a result, the price of the machine in the Miller Road shop became $330 and that in the Washington Road shop became $310.

Robinson's family could save a total of $1240 by buying 4 such washing machines from each shop during the offer period.

By how much was the price of the washing machine knocked down in each of the shops?

(a)Miller Road shop: __________

(b)Washington Road shop:_________
