Time taken by A to complete the work = (x × 3) = 3x days Time taken by B to complete the work = (2x × 3/2) = 3x days According to question, => (1/3x) + (1/3x) = 1/30 => (1 + 1)/3x = 1/30 => 3x = 60 => x = 20
3/7 Of 504 ÷ 12 + 17 = √?
436 × 794 – 68210 =? + 85730
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
(?)2 = {(26% of 35% of 3000) ÷ 3} × 91
22.5% of 300 + 32.5% of 4500 =?
25.6% of 250 + √? = 119
375% of 320 - 80% of 40 ÷ √256 = ?
1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
