Shankar comes to buy a T-shirt in a showroom. He purchases a shirt which costs ₹1,020 after a discount. He pays his bill in the form of 50 paise, 20 paise and 10 paise coins in the ratio 2 : 3 : 4 (assume for the sake of the problem). What is the number of 10 paise coins he used to pay his bill?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2040.
Let the number of coins be:
50 paise = 2x , 20 paise = 3x , 10 paise = 4x
Total value = (2x × 0.50) + (3x × 0.20) + (4x × 0.10) =
1x + 0.6x + 0.4x = 2x rupees
Given total = ₹1020
So, 2x = 1020 → x = 510
Number of 10 paise coins = 4x = 4 × 510 = 2040
