42, 48, 60, 84, 132,

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

(40/25) X 80 - ? = 45% of 300 - 55

311 × 17 = ? + 2482

5 + 2 × 3 ÷ (3 × 2) ÷ 4

36895 - 4256 - 2233 = ? 

Simplify the following expressions and choose the correct option.

2500 ÷ (5²) + 60% of 240 = ?

32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² = ?

? = 80% of 30% of (50 × 150) + 400

150% of ? + 280 ÷ 35 = 13² - 12² + 7

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

60% of 120 – ?% of 64 = 20% of 200

116 x (2/3)% of 420 + 666 x (2/3)% of 186 = 457 x (1/7)% of 126 + 555 x (5/9)% of 198 + ?
