Let the total work = 120 units (LCM of 20, 30 and 24) Amount of work done by Karan alone in one day = 120/20 = 6 units Amount of work done by Arjun alone in one day = 120/30 = 4 units Amount of work done by Krunal alone in one day = 120/24 = 5 units Amount of work done by Karan, Arjun and Krunal together in 3 days = 3 × (6 + 4 + 5) = 45 units Amount of work done by Arjun and Krunal together in 5 days = 5 × (4 + 5) = 45 units Remaining work = 120 – 45 – 45 = 30 units So, the time taken by Krunal alone to complete 30 units work = 30/5 = 6 days So, Krunal worked for 6 + 5 + 3 = 14 days
8 × 25% of ? = 400
?2 + 114 - 48 ÷ 2 × 5 = 163
1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2
Simplify the following questions:
(11) 8.5 × (121) 5.5 ÷ (1331) 5.5 = (11) ?
...(65% of 120) = 25% of ? - 22
Find the Value of
(60/15) × 25 + 152 – 18% of 200 = ?2
45% of 360 - 160 + ? = √324
Find the simplified value of the following expression:
14.25 × 32 – 11.4 × 15 + 8 – 712 ÷ 8 + 34.15 × 20 – 27 × 21 = ?
