If a cube of a number is subtracted from (153) , the number so obtained is 1457, Find the number.
Correct Answer:
A. 28
Explanation:
To solve the problem "If 20% of a = b, then b% of 20 is the same as:", follow these steps:1. Express the first statement as an equation: 0.20 \* a = b 2. Substitute this expression for b into the second part of the problem (b% of 20): (b / 100) \* 20 3. Replace b with 0.20a: ((0.20 \* a) / 100) \* 20 4. Simplify the expression: (0.20 \* a) \* (20 / 100) (0.20 \* a) \* 0.20 0.04 \* a 5. Convert the decimal back to a percentage: 0.04 is equal to 4%.Therefore, b% of 20 is the same as 4% of a.
