Question
A sold a car to B at 8% profit, who later sold it back
to A at 6% loss. If initially A purchased the car for Rs. 250000, then find the total profit earned by A in the transaction.Solution
Selling price of car when A sold it = 250000 X 1.08 = Rs. 270000 Selling price of the car when B sold it = 270000 X 0.94 = Rs. 253800 So, total profit earned by A = (270000 - 250000) - (253800 - 250000) = Rs. 16200
If 1560 ÷ 30 + 2025 ÷ 45 - z + 33 × 7 = 1848 ÷ 24 × 234 ÷ 39, then the value of z is:
25% of 140 + 2 × 8 = ? + 9 × 5
25% of 12% of 1600 + 112 = ? × 4Â
27% of 250 – 0.02% of 1000 is equal to:
