What would come next in the following letter series?
DWP, FUR, HST, JQV, _
In each group, 1st letter=2 places to the right of the first letter in the previous group 2nd letter=2 places to the left of the corresponding letter in the previous group 3rd letter=2 places to the right of the corresponding letter in the previous group
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
(115 × 17 × 3)/(23 × 51) + ?3 = √169
[192 ÷ 6 × 5] ÷ (? + 3) = 20
18 + 28÷ 4 - 14 = ? - 35
...26% of 650 + 15% of 660 – 26% of 450 = ?
(13)2 + 6 × (19)2 – 312 × 4 = ?
(23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
8888.88 + 888.88 + 88.88 + 8.88 = ? – 0.48
2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
