1*1/2 + 11*1/3 + 111*1/2 + 1111*1/3 + 11111*1/3 =?

150% of ? + 280 ÷ 35 = 13² - 12² + 7

120% of 25 + 80 X 2 = ?² - 6

Solve the following:

240 ÷ 4 × 512 ÷ 8

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

2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?

24 × √? + 4008 ÷ 24 = 40% of 200 + 327

If 960 ÷ 16 + 875 ÷ 25 - x + 28 × 6 = 1350 ÷ 18 × 222 ÷ 37, then the value of x is:

?² + 114 - 48 ÷ 2 × 5 = 163

30% of 40% of 120% of 3500 = ? × 63

13 X √? + 256 ÷ 4 = 30% of 900 - 50
