1500 × 60% of 25% = ? ² 

(880 ÷ 11 + 170) X ? = 40% of 1000 

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

(√1089 + 84 ÷ 2) % of 348 = 416 - ?

40% of 50 + 50% of ? = 25% of 300 - 10% of 250

81% of 2300 – 34% of 550 = ?

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

(12.09)² × 5.98 ÷ 26.95 = ? + 25 

65% of ? = 50 + 20 × 4
