Average of 6 numbers = 136 (average = sum of terms/number of terms) Sum of 6 numbers = 136 × 6 = 816 ---(1) Let the 6th number be x. Sum of 5 numbers = 7x From eq(1), 7x + x = 816 x = 816/8 = 102 The 6th number is 102.
20.05% of 220.05 – 15.15% of 99.99 × 2.02 = ?
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
(18 2 – 17 2) x (1/5) + ? = 148
What is the value of (6 + 4) ×12/4 + 5 – 3?
192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 250 + 26 ÷ 2 × ? = 207
84% of 8400 + 42% of 6120 =?
√(24²+285-8²-172) = ?²
