25.13% of 39.89% of 74.78% of 60.21% of ? = 44.89

1131.98 + ? – 1125.04 = 1364.93 – 1168.01

 15.78% of (287 + 302) + 12³ = ?% of 170 + 8 × 14 + 3² 

30.05% of 360.05 – 25.15% of 99.99 × 3.02 = ?

Solve the following expression and calculate the approximate value.

1727.8 + 2196.75 + 3 × 11.8 × 12.9 × 24.75

(?)² + 9.11³ = 31.9² – 39.03 

What approximate value will come in place of question (?) in the following given expression? You are not expected to  calculate the exact value.

(100.01% of 44.89) ÷ 14.98 = √? - √48.98

(2099.92 ÷ 25.02 of ? × 199.56 + 1199.95) = 3999.86

(22.93 × 11.92) + (17.78 ÷ 3.01) - (14.88 × 5.01) = ?
