Answer:
Marked price of the radio = Rs 1,600
Therefore, Selling price = (100 - 10)% x (100 - r%) x 1600
= (90/100) x [(100 - r) / 100] x 1600
Given, 1224 = 9/10 x (100 - r) x 16
=> 1224 x 10 / (9 x 16) = (100 – r)
85 = 100 - r
r = 15%

Answer:
Step-by-step explanation:
Marked price of the article = Rs 1,600
Therefore, Selling price = (100 - 10)% x (100 - r%) x 1600
= (90/100) x [(100 - r) / 100] x 1600
Given, 1224 = 9/10 x (100 - r) x 16
=> 1224 x 10 / (9 x 16) = (100 – r)
85 = 100 - r
r = 15%
