The registry keys that store the passwords are protected with Triple DES encryption, which uses your Windows login credentials as part of its cipher.
What will come in the place of question mark (?) in the given expression?
(30 × 5 + 20) × 2 = ?
?2 × 25 = 42 × 21 + 172
(? + 2180) ÷ 69 × 5 = 450
24% of 15% of 500 + 122 = ?2 – (232 ÷ 2)
{(300 ÷ 15)% of 1500} ÷ 6 = ? + 120
20% of 10% of 900 + 84/12 = ?2
(144 ÷ 4)² × (72 ÷ 12)³ = 12 ×? × (25920 ÷10)
Calculate the value of x2, if [(8 + 62) ÷ 4 of x + 2.5 × 5 = 42 + 20% of 10].
26 X √25 + 15 - 80% of 120 = ?2
