When is Buddhist Flag Day observed in India?

3.99² + (3.01 × 2.98) + ? = 225.03

– (8.002)³ + (30.001)² - (4.01)⁴ =?

(168.24 ÷ 23.98) x 19.81 + ? = 176.33

11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.27² 

What will be the approximate value of the following questions.

(89.90% of 479.88 - 2/5 of 400.11)² ÷ (50.11% of 359.77 + √224.85) = ?

[√ (121.23) ÷ √ (12100.04)] × √ 80.95 = 3/10 + ? ÷ 4

Which of the following options is the closest approximate value which will come in place of question mark (?) in the following equation?

? = 21.91% of (36.2 × (144.01 + 5.95)) + 16.71

21.11 × 4.98 + 22.03 × 4.12 – 31.95 + 95.9 × 3.02 =?

?% of 1499.89 + 54.14 × 8 = 25.05% of 5568.08
