The marked price of an article, which is bought at Rs.1280, is 25% above the cost price. If the certain discount is allowed and a
customer bought it for Rs. 1540 including 10% VAT, what is the
discount percent?

​

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
