Answer: C) 36 kmph Explanation: Given speed of the first train = 60 km/hr = 60 x 5/18 = 50/3 m/s Let the speed of the second train = x m/s Then, the difference in the speed is given by 503 - x = 12018 => x = 10 m/s => 10 x 18/5 = 36 km/hr

Answer: B) 84 Explanation: Ratio of girls and boys = 100% : 75% = 4:3 Difference is 1 unit = 35 So, 3 units = 35 x 3 = 105 If 20% absent, that’s mean 80% present. So, present boys = 80% of 105 = 80×105100 = 84

Answer: A) 0.625 Explanation: 5/8 is Nothing but to divide 5 into 8 parts.     As 5 is smaller than 8, the quotient starts with a decimal point to make 5 as 50 to be divisible by 8. (0.)     Now 50 goes for 6 times in 8 leaving a remainder 2. (0.6)      Again 2 is smaller than 8, As it already has decimal point in the quotient, now 2 becomes 20.      Now 20 goes for 2 times in 8 leaving a remainder 4. (0.62)      Again 4 is smaller than 8, As it already has decimal point in the quotient, now 4 becomes 40.     Now 40 goes for 5 times in 8 leaving a remainder 0. (0.625)     Therefore, the decimal value of 58 is 0.625.   Now find a decimal value of 1117 and Discuss your at Discuss.
