From the following figure, 
AB = ED = 480√3 AE = BD In Δ ABC, tan 30 = AB/BC 1/√3 = 480 √3/BC BC = 480 × 3 = 1440 In Δ EDC, tan 60 = ED/DC √3 = 480 √3/DC
29% of 400 + 66% of 1100 - 50% of 1200 = ?
382+ 482+ 572= ? - (81x 49)
(3/7) x 868 + 25% of 240 = (? + 65)
1 + 1 + 1/2+ 1/3 + 1/6 + 1/4 is equal to ____
2/5 of 3/4 of 7/9 of 14400 = ?
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
The value of (43-3× (4×6+12/6 ×6-4×5) +4)?
6% of 520 + 5% of 620 = ?
