Javed read 60 pages on the first day, which is 20% more than the pages read on the second day. If the second day's reading represents 1/6 of the total book, how many pages are in the book?
Let X be the pages read on the second day. We know 1.20 * X = 60, so X = 60 / 1.2 = 50 pages. Since 50 pages represent 1/6 of the total book, the total number of pages is 50 * 6 = 300. Therefore, the book contains 300 pages. This calculation confirms that option B is the correct answer.

Determine the number for which 7% of that number equals 21.
Let the unknown number be N. The problem states that 7% of N is 21, which can be written as 0.07 * N = 21. To solve for N, divide 21 by 0.07. This calculation results in 21 / 0.07 = 300. Therefore, 300 is the number that satisfies the given condition.

Calculate the value of x if x percent of 15 is equal to the sum of 30 and 5 percent of 300.
To solve this, first calculate 5% of 300, which is 15. Adding 30 to 15 gives 45. The equation becomes (x/100) * 15 = 45. Multiplying both sides by 100 gives 15x = 4500. Dividing by 15 results in x = 300. This confirms that 300% of 15 is indeed 45.
To find the value, multiply the percentages: 0.20 * 0.30 * 0.20 * 820. This equals 0.012 * 820, which results in 9.84. Among the provided choices, 9.80 is the closest numerical approximation to the calculated result of 9.84.

Determine the number for which 5% of the value is equal to 55.
To find the unknown number N, we set up the equation 0.05 * N = 55. Dividing both sides by 0.05, we get N = 55 / 0.05. Multiplying both numerator and denominator by 100 gives 5500 / 5, which equals 1100.

Jamal has traveled 20 km of a 40 km journey. Calculate the percentage of the total distance he has completed.
To find the percentage of the distance covered, divide the distance traveled by the total distance and multiply by 100. Thus, (20 / 40) * 100 equals 0.5 * 100, which is 50%.
137
Calculate the value of x if x percent of 60 is equal to 48.
To solve for x, we set up the equation (x/100) * 60 = 48. Multiplying both sides by 100 gives 60x = 4800. Dividing both sides by 60 results in x = 4800 / 60, which simplifies to 80. Therefore, 80 percent of 60 is indeed 48.

If a person's net income after a 5% income tax deduction is Rs. 1,373.70, what is their gross income?
The net income represents 95% of the gross income (100% - 5% tax). To find the gross income, divide the net income by 0.95. Calculating 1,373.70 divided by 0.95 yields 1,446. Thus, the gross income is Rs. 1,446.
139
If a person completes 10 km of a 25 km walk, what percentage of the total distance has been covered?
To keep expenditure constant, the product of price and consumption must remain unchanged. If the price increases by 25%, it becomes 1.25 times the original. To offset this, the new consumption must be 1/1.25 = 0.8 times the original, which represents a 20% reduction in consumption.
