The title of Section 6 of the Central Vigilance

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

65% of 460 − (3/4 of 160) = ?

√3600% of 150 + 3/5 of 360 - ? = 210

13 X ? = 85 X 4 + √81 + 2

{(80% of 650 + 25 × 12) – 20 × ?} = 760

120% of 400 + ?% of 520 = 1000

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

12.5 + 7.75 - 3.6 = ?

1885 ÷ 64.98 + 7.29 + ? = 69.09

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

{12² + (66/4) + (252/8)} ÷ 8 = (?)^1/2

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