Question 4.
  1. 5% of [50% of Rs 300] is

  1.    Rs.5
  2.    Rs.7.50
  3.    Rs10
  4.    Rs. 12.5
 Discuss Question
Answer: Option B. -> Rs.7.50
The given expression is: 5% of [50% of Rs. 300]
Using BODMAS rule, we perform the operation inside the bracket first and then simplify the expression further.
50% of Rs. 300 = (50/100) × 300 = Rs. 150
Now, we need to find 5% of Rs. 150.
To find 5% of a value, we can simply multiply the value by 5/100 or 0.05.
Therefore, 5% of Rs. 150 = (5/100) × 150 = Rs. 7.50
Hence, the correct answer is option B, Rs. 7.50.
Let's understand the concepts and formulas used in this problem in more detail:
  • BODMAS Rule: BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction. It is a rule used to simplify mathematical expressions with multiple operations. According to the rule, we must perform the operations in the following order:
  • Operations within the bracket
  • Exponents or powers
  • Division or multiplication (whichever comes first from left to right)
  • Addition or subtraction (whichever comes first from left to right)
  • Percentage: Percentage is a way of expressing a number as a fraction of 100. We use the symbol "%" to denote percentage. For example, 50% means 50/100 or 0.5.
  • Finding a percentage of a value: To find a percentage of a value, we can multiply the value by the percentage in decimal form. For example, to find 10% of 200, we can multiply 200 by 0.1, which gives 20.
By using the above concepts and following the BODMAS rule, we have simplified the given expression to find 5% of [50% of Rs. 300] as Rs. 7.50.

Question 7.
  1. A sells his goods 50% cheaper than B but dearer than C. Whose goods are the cheapest?

  1.    A
  2.    B
  3.    C
  4.    NONE OF THESE
 Discuss Question
Answer: Option C. -> C
Let's assume that B sells his goods at a price of $x$. As per the question, A sells his goods at 50% cheaper than B. Therefore, A's selling price would be 50% less than $x$, which can be calculated as follows:
A's selling price = $x - 50%$ of $x$A's selling price = $x - 0.5x$A's selling price = $0.5x$
Now, let's assume that C sells his goods at a price of $y$. As per the question, A's goods are dearer than C's goods. Therefore, A's selling price would be greater than $y$, which can be expressed as:
A's selling price > $y$
We have already calculated A's selling price as $0.5x$. Therefore, the above equation can be written as:
$0.5x > y$
We can further simplify the above equation as:
x > 2y
This means that B's selling price is more than twice the selling price of C. Hence, C's goods are the cheapest among the three.
To summarize:
  • B sells his goods at a price of $x$.
  • A sells his goods at a price of $0.5x$.
  • C sells his goods at a price of $y$.
  • A's goods are dearer than C's goods, i.e., $0.5x > y$.
  • B's selling price is more than twice the selling price of C, i.e., $x > 2y$.
  • Therefore, C's goods are the cheapest among the three.
Note: In this solution, we have assumed that the selling price of B and C is not related to each other. If there is any relation between their prices, then the answer may vary.If you think the solution is wrong then please provide your own solution below in the comments section .
