((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?

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

(18 × 8 ÷ 12) × 10 = ?

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

√? + 10 * 18 + 16 * 4 = 280

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

(? ÷ 16) = (20 ÷ ?) X 20

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

40% of 150 – ?% of 80 = 25% of 400

? = 0.05% of 12000 + 175% of 4800 – 13³ 

√14400 x √8100 - (60)² = ? + (80)²

√(?) ² = √7396 - √6889

74% of 2840 + 80% of 1640 - ?= 47²
