Who is the newly appointed chairman of Tata

40.02% of 1220.05 = ?² + 29.09 × 7.99

766/51 ÷ 387/42 × 121/13 = ?

12.99% of 499.99 ÷ 13.17 = ? ÷ 20.15

(129.98% of 8460) + (119.899% of 8640) = (130.009% of 15820) + ?

26.11% of ? – 521.02 = 648.51

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

41.99 x 22.01 ÷ √49.01 + ? = 13.99²

(29.98% of 9840) + ? + (19.899% of 8490) = 7560

(3/7 of 1049.88 + 44.95% of 799.79) ÷ (√168.89 + 24.77% of 400.11) = ?

233.98 + 73 × √35.95 - ? = 275.94 ÷ 3.99
