P – 20 days P – 6 unit Q – 24 days LCM = 120 Q – 5 unit R – 30 days R – 4 unit Work of all 3 per day is (6 + 5 + 4) – 15 units All worked for 4 days. So, 4 days work is 4 × 15 = 60 units Remaining work = 120 – 60 = 60 units That work done by Q and R their per day unit = (5 + 4) = 9 unit Remaining work done by Q and R is `60/9` days =`6 2/3` days
If 5√3+ √243 = 24.249, then what will be the value of √192+ 15√3.
17.6% of 250 + √? = 70% of 90
Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
(13)2 + 6 × (19)2 – 312 × 4 = ?
5760 ÷ 45 × 15 = ?
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
20% of (√9216 + ?) = 24
(18% of 360) ÷ 0.4 = ?
