Question
What will come in place of the question mark (?) in the
following series? 48, 291, ?, 399, 408, 411Solution
ATQ, 48 + 35 = 291 291 + 34 = 372 372 + 33 = 399 399 + 32 = 408 408 + 31 = 411
300% of (3341 – 471) = ? × (√4225/195)
1404 ÷ 26 x 3 + 7 = ?2
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
35% of 240 – 6 2 = ? 2 – √256
16 × 35 + 119 + 23 × 17 = ? + 370
{(? × 15) + (? × 45)} – 120 = 360
721 +21 x 9 - 118 = ? + 82
If a³ - b³ = (a - b)(a² + ab + b²), find a³ - b³ when a = 10 and b = 4.
`(450 -: ?)/(2.5 xx 1.2)` = 250
(750 / 15 × 15 + 152 + 20% of 125) = ?3
