If the occurrence of events follows Poisson Process

{(5/8) + (4/5)} × (?/19) = 33

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

? = 70% of 36% of (25 × 320) + 150

What should come in place of (?) question mark in the given expression.

(17² − 13²) ÷ (17 − 13) = ?

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

(7/9) of (15/4) of 480 = ?

60 % of 250 + √169 * 7 = ?² + 45 % of 160

30% of 60% of 1800 + 13 × 14 = (? ÷ 75) × 5

(25)² × 4 ÷ 5 + (3)³ + 48=? + 425

(7/4×18/21)+ (51/7× 28/17) + (25/2  × 48/10) =?

150% of ? + 280 ÷ 35 = 13² - 12² + 7
