Explanation:
Correct option 1: 26.67%
Given:
A person marks the price of his car 50% above the cost price.
He gives a discount of 8% and earns a profit of 10%.
Concept used:
Final percentage change after two successive increments of A% and 8% = (A+B+ AB/100)%
Calculation:
According to the concept,
50-B - (50B)/100 = 10 (Here, 8% discount is considered as a negative mark-up/increment)
=> 50-B -B/2 = 10
= 3B/2 = 40
=> B = 80/3
B ≈ 26.67
