C.P. = ₹ 5,400 and Rate of VAT = 8%
Let C.P. without VAT is ₹100, then price including VAT = 100 + 8 = ₹ 108
∵ When price including VAT is ₹ 108, then original price = ₹ 100
∴ When price including VAT is ₹ 1, then original price = 100/108
∴ When price including VAT is ₹ 5400,
then original price = 100/108 x 5400 = ₹ 5000
