On a certain item profit is 150%. If the cost price

135÷ 15 x 19 + 14807 = ? + √3249 - √9604

16 × 35 + 119 + 23 × 17 = ? + 370

(70% of 480) ÷ 6 + ? = 45% of 3500 + 80² + 27²

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

16² – 12 * 20 = 6 * ? - ³√8000

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

9 ^{(? + 12)} = 3 ^{(14 + 17 - 11)}

? ÷ [35% of 379 - 34(4/5)] = 0.4

116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?

25% of 300 + √(?) = 35% of 600 - 15% of 300

26 ² – 13% of 400 + (529 ÷ 23 ² ) = ? ²
