Mathematical Aptitude - Profit and Loss

>>>>>>>>Profit and Loss

• Option : C
• Explanation : Profit and loss formula is given by, Let S.P. of the car = x
Discount of 10%.
Profit = 8%.
∴ ((90/100)x – 135000/135000) × 100 = 8
⇒ (90/100)x – 135000 = 8 × 1350 ⇒ (90/100)x
⇒ x = 162000

• Option : D
• Explanation : Let C.P. of the article = 100
∴ Old S.P. = 108. New C.P. = 90. As the profit is 15%, so the new S.P. = 90 × 115/100 = 103.5. The difference in the two selling prices = 108 – 103.5 = Rs 4.5 If difference in S.P. is 4.5 then C.P. = 100. If difference in S.P. is 18, then C.P. = (100/4.5) × 18 = Rs 400.

• Option : D
• Explanation : SP = 90% of 8000 = Rs 7200
Profit = 7200 – 5000 = Rs 2200
Profit percentage = 2200/5000 × 100 = 44%
