33 × 5 - ?% of 250 = 62 - 6
Find the simplified value of the given expression.
(1/4) of {64 - 28 x 15 + 13 x 16 - 12.5 of 122}
- What will come in place of (?) in the given expression.
(14)² – (12)² = ? 32% of 4080 + 24% of 540 = ? % of 3200
350% of (450 / 1.5) = ?% of 4200
(15/8) x [6924 – 2124] + 910 = ? + 190
36 x 3.6 ÷ 0.5 ÷ ? = 64
(225 + 125) ÷ 7 + 250 = ? + 20% of 800
128 ÷ 22 × ? = 15% of 300 ÷ 9
135.37 – 50.24 + 629.09 – 199.50 = ? – 214.68 + 42.65
