Ram went to purchase 10 ball pens marked at ,₹6 per ball pen. find the price paid by Ram,if he pays a sale tax of12%.

Answer 1

Solution 1

MP of 1 ball = Rs. 6
MP of 10 balls = Rs. 60 

Sales tax = 12%
SP = [ (100+Sales tax) / 100 ] * MP
      = [ (100 + 12) / 100 ] * 60
      = [ 112/100 ] * 60
      = 1.12 * 60
      = Rs. 67.2

Solution 2

MP of 1 ball= Rs 6
MP of 10 balls = Rs. 60

Sales Tax= 12% of 60
               = 12/100 * 60
               = 0.12 * 60
               = 7.2

SP = MP + Sales tax
      = 60 + 7.2
      = Rs. 67.2
