Correct Answer: 42.85%

Solution : Given:
In a business, Alok gains 75% more profit than Akash.

Let us assume that Akash makes a profit of ₹ 100
The profit of Alok is 75% more than Akash.
Hence, profit of Akash = 100 + (75/100 × 100) = 100 + 75 = 175
So, profit earned by Alok over Akash = 175 – 75 = 75
% Profit earned by Alok over Akash = {(more profit earned by Alok) / total profit earned by Alok } × 100
= [(75 ÷ 175) × 100] %
= 0.42857 × 100%
= 42.85 %

Therefore, Akash earns 42.85% less profit than Alok. Hence, the fourth option is correct.
