⇒ (1845.89 + 3126.47 - 1280.35)

⇒ (4972.36 - 1280.35) = 3692.01

⇒ 3692.01 ÷ 5.25 ≈ 703.24

⇒ 703.24 × 3 ≈ 2109.72

⇒ 2109.72 = ? + 187.263

⇒ ? = 2109.72 - 187.263 ≈ 1922.46

Thus, the correct answer is 1922.5.

Approximate each term by rounding to the nearest whole number:

49.95 ≈ 50

12.12 ≈ 12

19.98 ≈ 20

7.95 ≈ 8

1.98 ≈ 2

60.05 ≈ 60

Calculate each component:

First term: 50 × 12 = 600

Second term: 20 × 8 = 160

Third term: 2 × 60 = 120

Combine the terms:

600 - 160 - 120 = 320

Thus, the correct answer is 320.

Given Expression:

18.45² + ∛(729.08) + 89.32 = ?² - 42.99

Approximate each term:

18.45² ≈ 340.2 (since 18.45 × 18.45 ≈ 340.2025)

∛729.08 ≈ ∛729 = 9

89.32 stays as is

LHS: 340.2 + 9 + 89.32 = 438.52

⇒ 438.52 = ?² - 42.99

⇒ ?² = 438.52 + 42.99 = 481.51

√481.51 ≈ 21.93 ≈ 22

Thus, the correct answer is 22.

Approximate the numbers:

189.84 ≈ 190

327.11 ≈ 327

215.96 ≈ 216

4.98 ≈ 5

Perform the left-side calculation:

190 + 327 = 517

517 - 216 = 301

301 + 5 = 306

Set up the equation:

306 = 9 × ?

Solve for ?:

? = 306 ÷ 9 = 34

Thus, the correct answer is 34.

Simplify the right-hand side:

⇒ 428 - 195 = 233

Simplify known values on the left-hand side:

⇒ 23² = 529

⇒ √624 ≈ 24.98 ≈ 25 (approx)

Plug into the equation:

⇒ (?) × 17.93 - 529 + 25 = 233

⇒ (?) × 17.93 - 504 = 233

⇒ (?) × 17.93 = 233 + 504 = 737

⇒ ? = 737 ÷ 17.93 ≈ 737 ÷ 18 ≈ 41

Thus, the correct answer is 41.

Follow BODMAS rule to solve this question, as per the order is given below:

Step-1: Parts of an equation enclosed in 'Brackets' must be solved first and in the bracket,

Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated

59.89% of 4500 + 39.96% of 6500 – 79.87% of 5500 = ?

⇒ 60% of 4500 + 40% of 6500 – 80% of 5500 = ?

⇒ 2700 + 2600 – 4400 = ?

⇒ 5300 – 4400 = ?

⇒ ? = 900

Follow BODMAS rule to solve this question, as per the order given below,

Calculations:

[(15.8 × 2.87) ÷ 3.984 – 1.230 ÷ 1.265] = ? × 1/2

After approximation:

(16 × 3) ÷ 4 - 1 ÷ 1 = ? × 1/2

⇒ [48 ÷ 4 – 1] = ? × 1/2

⇒ [12 - 1] × 2 = ?

⇒ 11 × 2 = ?

⇒ ? = 22

∴ The value of ? is 22.

Approximating the numbers in the above expression:

⇒ (1800 + √? × 30) ÷ 15 = 144

⇒ 1800 + √? × 30 = 144 × 15 = 2160

⇒ √? × 30 = 2160 – 1800 = 360

⇒ √? = 360/30 = 12

∴ ? = 12² = 144
