Which two numbers from amongst the given options should

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

? = 90% of 25% of (40 × 200) + 300

30% of 40% of 120% of 3500 = ? × 63

`(256/6561)<sup>(1/4)</sup> = ?`

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

√144 X √324 + ? = 8³ + 31 X √16

(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²

72.5% of 400 – 23.25% of 1020 = 105% of ?

5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630

800 + 900 X (3)^-2 - ? = 25 X 60 ÷ 2 

? = 6.25% of 240 + 25² + 17² – 16 × 17

1500 ÷ 15 + 1000 ÷ √100 + ? = 250 * 3
