Under a sale offer, Suresh was offered 20% discount on the part of the marked price that was paid in cash, but was charged 0.5% on the part of the marked price paid through a credit card. If Suresh paid 40% of the marked price in cash and the rest through a credit card, what percentage of the marked price was his total final payment?

92.3%

Let the marked price = Rs. 100

40% of MP is paid in cash = Rs. 40 is paid in cash

Rs. 60 is paid by credit card

According to the question,

20% offered on the part of the marked price that was paid in cash =  20% of 40 = 8

The discount price of the product paid by cash = 40 - 8 = Rs. 32

0.5% charged on the part of the Marked Price that was paid by card

= 0.5% of 60 = 0.3

The increased price the of product paid by credit card = 60 + 0.3 = 60.3

Total payment Suresh has pay = payed by cash + payed by credit card

⇒ Rs. 32 + Rs. 60.3 = Rs. 92.3

Percentage % = \(\frac{92.3 × 100}{100}\) = 92.3%
