14 i think. Since 7/20 is 35%, it’s 40-65%(100%-35%) and so it is 14 red marbles.

Mira buys a gold ring for ₹ $8740$ inclusive of $15\%$ tax. The ring was sold at a discount of $5\%$ .
Sloan [31]

The marked price of the ring given the cost as 8740 inclusive of 15% tax and discount of 5% is $7,283.3.

<h3>Marked price</h3>

  • Cost of the gold ring = $8740
  • Tax = 15%
  • Discount = 5%
  • Marked price = x

8740 = x + (15% of x) + (5% of x)

8740 = x + (0.15x) + (0.05x)

8740 = x + 0.15x + 0.05x

8740 = 1.20x

x = 8740 / 1.20

x = 7283.33333333333

Approximately,

x = $7,283.3
