If 28957.5 ÷ 268.125= 108, then 289.575 ÷ 2681.25 is equal to:
72 – 4(40 + 24 ÷ 6 × 6 – 4 × 4) + 40
42% of 400 + 38% of 800 + ?2 = 728
√4761 ÷ 23 + √12769 = ? × 58
(106 + 14)/15 = ?/5
What will come in the place of question mark (?) in the given expression?
? = 90% of 25% of (40 × 200) + 300
400 % of 20 + 65 % of 620 - 92 × 5 = ?
525 ÷ 21 x 28 – 853 + 264 = ?
