‘Aman’, ‘Bishnu’ and ‘Chintu’ will complete the whole work in 20 days (4/0.20), 36 days (9/0.25) and 45 days (27/0.60) respectively. Let total amount of work = 180 units (LCM of 20, 36 and 45) Amount of work done by ‘Aman’ in one day = 180/20 = 9 units Amount of work done by ‘Bishnu’ in one day = 180/36 = 5 units Amount of work done by ‘Chintu’ in one day = 180/45 = 4 units Amount of work done by ‘Aman’, ‘Bishnu’ and ‘Chintu’ together in 4 days = 4 × (9 + 5 + 4) = 72 units Time taken by ‘Chintu’ and ‘Bishnu’ together to complete the remaining work = (180 – 72)/(5 + 4) = 12 days
2048 × 1824 ÷ 76 = (? - 212) × 64
22 + 60 × 3 ÷ 12 = ?
17% of 250 + ? = 108
(5/8 of 480 - 30% of 420)² ÷ (√81 + 25% of 320) = ?
(1296 ÷ 54 × 24 + 24) = ? × 150
(18 2 – 17 2) x (1/5) + ? = 148
Find the value of the given expression.
[76 – {90 ÷ 5 × (24 – 36 ÷ 3) ÷ 3}]
∛857375 + ∛91125 = ? + √6889
20 × 224÷ 16 – 50 = ? + 100
...2850 ÷ 2.5 - ? × 42 = 300
