ATQ, Part of the task done by Akash and Bittu in one day = (1/40) + (1/50) = 9/200 Part of the task done by Akash and Bittu in 10 days = 90/200 Remaining work = 1 – (90/200) = 110/200 Let the time taken by Chinky alone to complete the work be ‘d’ days. So, (90/200) + (10/d) = 110/200 10/d = (110/200) – (90/200) d = 100 So, time taken by Chinky alone to complete the task = 100 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
