ATQ, Time taken by ‘Abhijeet’ to achieve the target alone = 8/0.25 = 32 days Time taken by ‘Vivek’ to achieve the target alone = 0.5 × 32 = 16 days Time taken by ‘Chirag’ to achieve the target alone = 16 + 4 = 20 days Let the total target achieved be 160 units Efficiency of ‘Abhijeet’ = 160/32 = 5 units/day Efficiency of ‘Vivek’ = 160/16 = 10 units/day Efficiency of ‘Chirag’ = 160/20 = 8 units/day For statement I: Time taken by ‘Abhijeet’ and ‘Chirag’ together to achieve 81.25% of the target = 0.8125 × (160/13) = 10 days Therefore, statement I is true. For statement II: Time taken by ‘Vivek’ and ‘Chirag’ to achieve 90% of the target together = 0.9 × (160/18) = 8 days Therefore, statement II is true. For statement III: Time taken by ‘Abhijeet’ is 12 days more than ‘Chirag’. Therefore, III is true.
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
