16% of 250 + 32% of 500 = ?
345 × 20 ÷ 4 + 28 + 60 = ?
1299.999 ÷ 325.018 × 24.996 = ?
33 × ?2 – 6 × 5 = 3270
14 × 11 + 25 – ? = 21% of 300
Find the simplified value of the given expression:
(5 + 13 of 7 - 5.25 of 8 + 63) ÷ 18
961 × 4 ÷ 31 – 15% of 180 = ? – 73
262 × 15 + (?)² = 4099
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128
