Let the eight numbers be a, b, c, d, e, f, g, h According to the question, (a+b+c+d+e+f+g+h)/8 = 5.95 a + b + c + d + e + f + g + h = 47.6 ……………. (i) (a+b)/2 = 5.4 a + b = 10.8 ……. (ii) (c +d)/2 = 5.86 c + d = 11.72 …… (iii) put the value of eq (ii) and (iii) in (i) e + f + g + h = 47.6 – 10.8 – 11.72 = 25.08 Average = 25.08/4 = 6.27
11.89 × 2.10 × 4.98 × 4.03 ÷ 7.98 of 15.03 = ?
9.8 × 77.9 ÷ (2.3)2= ?
26.23 × 31.82 + 44.8% of 1200 + ? = 1520
15.1 + 3.97 – 9.07 × 1.96 = √?
? = 49.99² ÷ (1.98⁵ + 8.01 × 89.91) + 75.15% of (263.89 × 49.11)
480.11 ÷ 15.98 × 5.14 – 134.9 = √?
(?)2 + 3.113 = 22.92 – 61.03
20.11% of 119.99 + √80.97 ÷ 3.02 = ?
(256.19 ÷ 63.99) 2.05 X (7.99) = 2 ? + 2.05
15.05% of 1599.88 + 29.99 × 12.01 - 420.05 = ?
