Who among the following applied European theatrical techniques to Indian Classical dance with folk and tribal dance?

[(17.97)² ÷ 47.67 X 11.67] ÷ 26.85 = ?² - (10.98 X 65.98)

√27889.11 × √575.9 – (21.02)²  =? × 2.95

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

1080.04 – 480.18 + 449.98 ÷ 15.06 = ?

25.19% of (?² ÷ 38.87 × 4679.94) = 6299.82 ÷ 419.78 × 50.15

9.95% of 1299.99 + 19.95 × 17.05 - 299.99 = ?

20.05% of 150.05 – 12.15% of 99.99 × 2.02 = ?

?% of (136.31 ÷ 16.97 × 75.011) = 179.98

70.14% of 799.95 - 240.12 = ? + 40.17% of 299.95

83.781 `xx` 728.910 `-:` (3.008)² = ?
