16/15 of 21/28 of 321.5 =
? What will come in place of the question mark (?) in the following expression?Solution
ATQ, 16/15 of 21/28 of 321.5 = ? 16/15 × 3/4 × 321.5 = ? 4/5 × 321.5 = ? ? = 257.2
What will come in the place of question mark (?) in the given expression?
(18 × 8 + 24) × 4 = ?
215 + 378 – 23 + 15 - 27 = ? + 3² + 16²
Simplify the following expressions and choose the correct option.
 (96 ÷ 8 + 72 ÷ 9) * 3
82% of 400 + √(?) = 130% of 600 - 85% of 400

13 X √? + 256 ÷ 4 = 30% of 900 - 50

612 + 1250 - 728 = ? × 63
- What will come in place of the question mark (?) in the following questions?
75% of 240 + 30 = ? 16 × 14 + 30 × 21 = 14 × ?
