Five students are sitting in a circle facing the center.

1500 × 60% of 25% = ? ² 

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

{12² + (66/4) + (252/8)} ÷ 8 = (?)^1/2

2 X 25 + (30% of 80) ÷ (10% of 120) = ?

289 + 896 + 144 – 25% of 1100 =?

Find the value of the expression:

18 + 12 – 4 × [22 + 6 – 2 × (38 – 23)]

{640 of 8 - (12)² of 6} - 900 = ?

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

√625 + 12 × 5 = ?

666(2/3)% of 30 - 116(2/3)% of 90 =?

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

40% of 150 - ?% of 75 = 15 × 1.6

6 × 5.5 + 4.5 × 20 - 102 = ?
