To solve (?)³ × (5⁵) ÷ 225 = 3000, follow these steps:
- Rearrange the equation:
(?)³ = (3000 × 225) ÷ 5⁵ - Calculate 5⁵:
5⁵ = 3125 - Simplify the numerator:
3000 × 225 = 675000 - Divide:
675000 ÷ 3125 = 216 - Find the cube root of 216:
√³(216) = 6

- First, calculate 8% of 800: 8/100 * 800 = 64.
- Now, the equation is 64 * ? = 224.
- To solve for ?, divide both sides by 64: ? = 224 / 64.
- This simplifies to ? = 3.5.
- So, the correct answer is 3.5, which corresponds to option 2.

According to the problem:
- The sum of the digits is 8:a+b=8
- When the digits are reversed, the number is decreased by 54. The number with reversed digits is 10b + a. So:10a+b−(10b+a)=54Simplifying this equation:10a+b−10b−a=54
9a−9b=54
a−b=6
Now, we have two equations:
- a+b=8
- a−b=6
Add these two equations:
(a+b)+(a−b)=8+6
2a = 14
a=7
2a = 14
a=7
Substitute a=7 into a+b=8:
7+b=8 , b = 1
So, the number is 10a+b=10×7+1=71
Answer: The number is 71.

Understanding the Problem
To solve the expression √785 + √729.50, we need to approximate the square roots of both numbers.
Approximation of √785
- √785 is close to √784, which is exactly 28 (since 28 x 28 = 784).
- Thus, we can estimate √785 to be slightly more than 28, approximately around 28.03.
Approximation of √729.50
- √729 is exactly 27 (since 27 x 27 = 729).
- Since 729.50 is slightly greater than 729, we can estimate √729.50 to be slightly more than 27, approximately around 27.01.
Adding the Approximations
Now, we will add the approximated values:
- √785 ≈ 28.03
- √729.50 ≈ 27.01
So,
- 28.03 + 27.01 = 55.04
Conclusion
Rounding off 55.04 gives us approximately 55. Therefore, the answer to the equation √785 + √729.50 is closest to option 'B', which is 55.
This method of approximation allows us to quickly assess the problem without needing to calculate the exact square roots.

The given expression is:
(4.669 × 4.669 - 2.331 × 2.331) / ((4.669)² + (2.331)² - 4.669 × 4.662)
(4.669 × 4.669 - 2.331 × 2.331) / ((4.669)² + (2.331)² - 4.669 × 4.662)
- Numerator:
4.669 × 4.669 = 21.794
2.331 × 2.331 = 5.433
21.794 - 5.433 = 16.361 - Denominator:
(4.669)² = 21.794
(2.331)² = 5.433
4.669 × 4.662 = 21.748
21.794 + 5.433 - 21.748 = 5.479 - Final Calculation:
16.361 / 5.479 ≈ 2.99
