(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
=> (15 × 225)/(45 × 5) + 480 = ? + (25/100) × 1240 ` ` => 15 + 480 = ? + 310 => ? = 495 – 310 => ? = 185
(? + 2180) ÷ 69 × 5 = 450
85% of 620 + ? % of 1082 = 4855
1780 – 60 ÷ 4 x 80 = ?
If x²y² + (1/ (x2y2)) = 83, then the value of xy – 1/xy is:
25% of 300 + √(?) = 35% of 600 - 15% of 300
(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²
26% of 950 + 50/3% of 7962 = ?
((8)0- (0.1)-1)/( (6/16)-1 ×(3/2)3+ ((-2)/6)-1) = ?/2
(23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
