According to Question; Efficiency of pipe ‘A’ = (210/15) = 14 litres/hour Efficiency of pipe ‘C’ = 14 ÷ 1.25 = 11.2 litres/hour Efficiency of pipe ‘B’ = 11.2 × 1.5 = 16.8 litres/hour Time taken by all the pipes together to fill the tank = {210/(14 + 11.2 + 16.8)} = (210/42) = 5 hours Or, time taken by all three pipes together to fill the tank = 5 × 60 = 300 minutes
386.99 + 397.99 + ? - 232.02 = 35.02 × 31.99
(9/20 of 3998.93) - √2499.57 + (17.87% of 1199.67) = ?
? = 28.04² ÷ (4.01⁵ + 9.89 × 20.20) + 84.56% of (198.76 × 30.03)
24.75% of 639.87 + (299.98 ÷ 2.5) = ?2 + 24.18
? = 782.24 + 1243.97 – 19.992
`(sqrt(960.87)xx9.932+sqrt(629.998)xx26.385)/(sqrt(1028.902)xx4.977)=?`
?2/3 = 33.33% of 107.99 + 45.45
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
18.22 × 7.99 + 156.15 = ?
