Maximum amount in pulses is produced in which Indian

32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² =?

(〖(0.4)〗^(1/3)  × 〖(1/64)〗^(1/4)  × 〖16〗^(1/6)  × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3)  × 4^(-1/2)  ×〖1024〗^(-1/4) ) = ?

(30 × 0.80)⁴ ÷ (2160 ÷ 60)⁴ × (54 × 16)⁴ = (6 × 4)^?+5

What will come in place of the question mark (?) in the following expression?

?% of 600 + 15 × 28 = 30% of 1800

(3984 ÷ 24) x (5862 ÷ 40) = ?

108 ÷ ? + 156 ÷ √144 = √64 × 2

√(8²  × 7  × 5² - 175) = ?

4.2 × 6.5 × 7.8 = ?

I. x² + 3x – 154 = 0

II. y² + 5y – 126 = 0

18 × √225 + 378 ÷ √441 = ? × 9
