100, 125, 143, 169, 198, 230, 265
The pattern of the series is: 100 + 20 = 120 120 + 23 = 143 143 + 26 = 169 169 + 29 = 198 198 + 32 = 230 230 + 35 = 265 The pattern for the differences is: 20 + 3 = 23 23 + 3 = 26 26 + 3 = 29 29 + 3 = 32 32 + 3 = 35 Hence, the wrong number is 125.
[(15)³ × (8)²] ÷ (90 × 6) = ?²
2856 ÷ 34 = ?% of 240
9 × 40× 242 × 182= ?2
(6 × √361) × 2.5 = ? + 125
255 × 8 + 386 × 5 =? % of 7940
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 ×9.05 =?
40% of 1820 + 80% of 630 = 90% of 1280 + ?
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
25% of 140 + 2 × 8 = ? + 9 × 5
