Who is the MD & CEO of Central Depository Services

? = 41.92% of (34.92 x 40.42) + 29.78% of 399.84

2380.03 ÷ 84.98 x 39.9 = ? + 15.32

15.98% of 2199.9 = √? + 17.02% of 1799.97

14.96% of 120.03 - 107.99 + 88.93% of 199.87 = ?

11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.27² 

What will be the approximate value of the following questions.

(√143.74 + 29.89% of 720.27) × (5/9 of 539.79) = ?

12.06 × 19.02 + 12.94 × 14.87 + 152.09 = ?% of 498.98 

? × [(16.87) ² – (6.98) ² ] = 5.04× 191.11

What will be the approximate value of the following questions.

(89.90% of 479.88 - 2/5 of 400.11)² ÷ (50.11% of 359.77 + √224.85) = ?
