Question : The marked price of the car is Rs. 6,00,000. Rahul buys that car at two successive discounts of 30% and 20%. If after using the car, he sells the car for Rs. 4,78,000, then what is the profit percentage?
Option 1: 39.87%
Option 2: 36.85%
Option 3: 33.33%
Option 4: 42.26%
Correct Answer: 42.26%
Solution : Single equivalent discount = $(x+y-\frac{xy}{100}$)% where $x$ and $y$ are two successive discounts. So, two successive discounts of 30% and 20% are equivalent to (30 + 20 – $\frac{30×20}{100}$) = 44% Purchased price = Marked price – 44% of Marked price = 600000 – 0.44

Option 2: 5000
Option 3: 4500
Option 4: 5500
Correct Answer: 5000
Solution : Let the number of boys be $x$ The number of girls = 6000 – $x$ Now, 60% of $x$ + 90% of (6000 - $x$) = 65% of 6000 ⇒ 0.6$x$ + 0.9(6000 – $x$) = 0.65 × 6000 ⇒ 0.6$x$ + 5400 – 0.9$x$
