A person had to multiply two numbers. Instead of

500% of (121.8 + 16.4 – 28.2) = ? × 2

150% of 84 + ?% of 130 = 230

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

(72 × 4 – 92) ÷ 14 = ?

33 × ?² – 6 × 5 = 3270

(3500 ÷ √1225) × √(20.25) = ? ÷ 4

What is 12% of 4% of 7% of 2 x 10⁶ ?

Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.

42 * 7 * 64 * 11 * 6 *4

Find the simplified value of the given expression:

7 of 9 ÷ 3 × 5² + √81 – 14

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

(12.09)² × 5.98 ÷ 26.95 = ? + 25 

10% of 100 + 14 = ?% of 120
