? × 5.5 = √1225 + 40% of 30% of 37.5% of 5000 –

Simplify:

(3/5 of 250) + (25% of 160) - (0.2 of 150)

36% of 250 + 26 ÷ 2 × ? = 207

What will come in the place of question mark (?) in the given expression?

[{(24) ² ÷ (6) ² } ÷ 8]⁴ = ? ÷ 5

134% of 1250 – 46% of 2120 = 4 × ?

(22 + √3364)/(? + 4) = 10

What value should come in place of (?) in the given expression.

√784 + (32 × 6) − (56 ÷ 7) = ?

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

45 × 2 + 180 ÷ 6 − 12 = ?  

14 × 11 + 25 – ? = 21% of 300

52% of 36% of 810 = 72% of 18% of ?
