- (15.99)2 + 219.98% of 20.01 = ?2 × 75.01% 
- 125.9% ÷ 9.05 x 99.98 = ? - 69.97 × √324.02 ÷ 5.98 
- 41.98% of 2200.031 + 15% of 3999.9 = ? 
- (2099.92 ÷ 25.02 of ? × 199.56 + 1199.95) = 3999.86 
- 15.232 + 19.98% of 649.99 = ? × 4.99 
- ?² × 55% of (29 + 32 - 41) = 41.66% of 216 + 9 
- What approximate value will replace the question mark (?) in the following? - ? –... 
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.) 
- 6106.11 ÷ √? × 55.9 = 3976.21 
- 24.99 × 32.05 + ? - 27.01 × 19.97 = 29.99 × 27.98
