The desire for new experience is the desire for variety

? = 25.08 + 11.99 × 24.07

What approximate value should come in the place of question mark (?) in the following questions?

41.99 x 22.01 ÷ √49.01 + ? = 13.99²

√3970 × √730 - √2400 = ?

What approximate value will replace the question mark (?) in the following?

80.09 * √144.05+ ? * √224.87 = (2109.09 ÷ √1368.79) * 19.89

Approximate the value of (19.98 × 5.02) ÷ 0.99

2 (1/4)% of 7999.78 + {49.77% of 899.71} + √144.14 - 20% of 1499.83 = ?

11.89 × 2.10 × 4.98 × 4.03 ÷ 7.98 of 15.03 = ?

(29.97%) of 9840 + ? + (45.17% of 1240) = (31.955% of 11750)

15.23² + 39.98% of 539.99 = ? × 6.99
