59.978% of 800.315 - 229.95 = ? - 24.95% of 200.15

44.89% of 600.25 + (29.98 × 5.67) + (√1940 – 10.29) = ?²

Which of the given trigonometric identities is incorrect ?

1. tan² θ = sec² θ - 1B. cosec² θ = 1 + cot

? + 539.76 ÷ 5.4 × 94.80 = 9829.54

(? + 6.06^3.03 ) ÷ 10.08 + 21.89 × 6.97 = 1979.97 ÷ 10.96

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

? = 200.24 + 1077.97 – 14.99²  

350 ÷ 5 + 30 % of 180 + ? * 12 = 48 * √16

95.001% of 8219.99 - 4/9 % of 5399.98 + 109.99 = ?
