According to the question, Let length of train be ‘x’ m. => (Speed of train – Speed of man) = Length of train/Time => (78 - 6)× (5/18) = x/23 => 20 = x/23 => x = 460 Length of train is 460 meter.
(42% of 1500 + 170) ÷ 4 = ?2 - 52
55% of ? = 45 + 20 × 6
If 960 ÷ 16 + 875 ÷ 25 - x + 28 × 6 = 1350 ÷ 18 × 222 ÷ 37, then the value of x is:
4/5 + 6/7 × 14/42 ÷ 24/35 = ?
Find the value of 16 x [(8 - 5) of 12 ÷ 4].
√676 + (0.75 × 80) + (72 ÷ 3) = ? - 82
?% of 140 + 16% of 250 = 62 × 12
[(15)³ × (8)²] ÷ (90 × 6) = ?²
