Tell me the discount for the following items. 1. A piano is sold at 70% of the original price.

Hello: (1) A piano is sold at 70% of the original price. (Note: original price 100%, i.e. 10% discount)

Process: 100 %× 70 %× 10 = 7.

So the piano is 30% off.

(2) A TV set is sold at 95% of the original price.

100%×95%× 10=9.5

So the TV set is 15% off.

I hope so, O(∩_∩)O Thank you.
