Mathematical Aptitude - Profit and Loss
- Option : C
- Explanation : The ratio of production between women and men is
60:40.
The profit on men’s garments = 9% of Rs 40 = Rs 3.6
To make profit of 5%, contribution of women’s garments = 5 – 3.6 = Rs 1.4
Profit percentage on women = 1.4/60 × 100 = 2.33%
- Option : A
- Explanation : Old sales price = 500 + 40% of 500 = Rs 700
New marked sales price = 500 + 80% of 500 = Rs 900
Discounted price = 900 – 20% of 900 = Rs 720
Thus new price is higher by Rs 20
- Option : A
- Explanation : 20% reduction on Rs 600 means benefit of RS 120 to a
customer. That enables customer to buy 2 kg extra
article.
Thus reduced selling price of 2 Kg = Rs 120 and of one Kg = 120/2 = Rs 60
If a value reduces by 20%, it means it should be increased by 25% to reach at original value again.
Thus original price = 60 + 25% of 60 = Rs 75
- Option : A
- Explanation : Hint: Original CP can be calculated first, that is
Rs 50000.
Then CP increases by 5%. Same amount of profit can be added to it, and then percentage calculated on it.
- Option : C
- Explanation : Cost Price = (1680/84) X 100 = Rs 2000
Marked price = 2000 X (115%/92%) = Rs 2500
