After India, which country was the second most

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

?% of 2480 + 15 × 34 = 1440

(8² + 6² ) × 1.25 + 20% of 145 = ? – 40% of 65 

Evaluate: (768÷16)×(125÷25)−(81÷9)×12

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

40% of (120 + 80) + 25% of 160 = ?

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

(³√1728 * 25) ÷ 3 * ? = 250 + 50* 3

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

65% of 900 - 45% of 600 = ? X 3 

Simplify the expression:

(9x² - 25) / (3x + 5)

[{(3 × 54 × 21)/63} + 6] / 6 = √? 

3.2% of 500 × 2.4% of ? = 288
