Sign in nowLet the capacity of the tank be ‘150’ litres {LCM (25, 30)} Efficiency of pipe ‘A’ = (150/25) = 6 litres/minute Efficiency of pipe ‘B’ = (150/30) = 5 litres/minute Quantity of water filled by pipe ‘A’ in 18 minutes = 18 × 6 = 108 litres Quantity of water to be filled = 150 – 108 = 42 litres Time taken by pipe ‘A’ and ‘B’ together to fill 42 litres of water = {42/(6 – 1)} = 42 minutes Total time taken = 18 + 42 = 60 minutes
If (i) P is taller than Q, (ii) R is shorter than P, (iii) S is taller than T but shorter than Q, then who among them is the tallest?
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
? ÷ 62 × 12 = 264
(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²
15 * 12 + 35% of 80 + 70% of 130 = ?
(3/7 )Of 3360 ÷ 240 + 30 = (?)²
(144 ÷ 4)² × (72 ÷ 12)³ = 12 ×? × (25920 ÷10)
