Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 30%

Let  marked price of a chair and a table are be 2x and 3x

A/C to question 

2x × 80% + 3x × (100 - A)% = (2x + 3x) × 74%

160x/100 + 3x × (100 - A)/100 =370x/100

{160x + 3x × (100 - A)}/100 = 370x/100

3x × (100 - A) = 370x - 160x

100 - A = 210x/3x

100 - 70 = A

A = 30%
