Here, the shirts have the same marked price - Let's call it M.
The amount that the shop will make selling the 6 shirts(at their original price) is 6M.

The shirts are sold at 0.9M, 0.8M, and 0.7M to the customers as discounts of 10%,
20%, & 30% are offered to the customer who bought 1,2, & 3 shirts respectively.

The cost recovered after the discounts is 0.9M + 0.8M*2 + 0.7M*3 = 0.9M + 1.6M + 2.1M = 4.6M
This causes a loss of 1.4M (6M - 4.6M) to Mohanlal because of the discounts given to the customers.

Therefore, the approximate value of the discount in percentage is \(\frac{1.4M}{6M}*100 = \frac{70}{3} = 23\)%(approx) (Option B)
