What is the full form of CVC written on the credit cards?
Card Verification Code (CVC) is a 3 or 4 digit code that protects your credit card from possible fraud. 
(2/7)% of 5600 ÷ √ 64 = ?
7(1/7)% of 3500 + 6(2/3) % of 6000 = ? + 552.5
If x²y² + (1/ (x2y2)) = 83, then the value of xy – 1/xy is:
12.5% of 384 - 16.66% of 66 = √16 + √? + 22
242 + 80% of 1620 = ? × 16 – 35% of 800
82.3 × 644.7 × 723.4 × 815.85 = 72?
(42% of 1500 + 170) ÷ 4 = ?2 - 52
? ÷ [35% of 379 - 34(4/5)] = 0.4
9/5 × 18/25 ÷ 42/21 = ? - 82/75
