Question
Train 'X' leaves Pune heading to Nagpur at 7:00 a.m. At
9:00 a.m., Train 'Y' leaves Nagpur for Pune, traveling at 70 km/h. The trains meet at 2:00 p.m. If the total distance between the two cities is 770 km, what is the speed of Train 'X'?Solution
ATQ,
Let the speed of train 'X' be x km/h Distance covered by train 'X' in the first 2 hours = 2 Γ x = 2x km Time both trains traveled towards each other = 2:00 p.m. - 9:00 a.m. = 5 hours So according to the question: 5 Γ (70 + x) = 770 - 2x β 350 + 5x = 770 - 2x β 350 + 5x + 2x = 770 β 7x = 420 β x = 60 So, speed of train 'X' = 60 km/h
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
β323.89 Β Γ (3.20) Γ· 9.02 =?
24.11% of 249.99 + β143.97 Γ· 12.02 = ?
Β 5983.987 + 59832.999 β 598.873 = ?
(100.01% of 44.89) Γ· 14.98 = β? - β48.98
(5.013 β 30.04) = ? + 11.98% of 4799.98
(4096)1/3 × 10.11 × 11.97 ÷ 24.32 = ? + 15.022
- β81.45 + β225.60 + 49.89% of (520.43 + 22.13% of 131.45) = ?
40.024 of 54.89% of 19.9 = ? Γ β(2661.98/22.09)Β
Find the approximate value of Question mark(?) for given equation.Β
135.86% of 249.99 + 24.95 Γ 14.03 Γ· 2.01 = ?
