"A)30km/hr",
"B)35km/hr",
"C)25km/hr",

] | B | Explanation:
time =1 hr 40 min 48 sec
=1 hr +4060 hr +48/3600 hr
=1+2/3+1/75=126/75hr
distance =42 km
speed=distance/time=42(126/75) =42×75/126=25 km/hr=25 km/hr
⇒57 of the actual speed =25
⇒ Actual speed =25×7/5=35 km/hr

aquarat_30140 | aquarat | Two stations P and Q are 110 km apart on a straight track. One train starts from P at 7 a.m. and travels towards Q at 20 kmph. Another train starts from Q at 8 a.m. and travels towards P at a speed of 25 kmph. At what time will they meet? | [
"A)10.30 am",
"B)10 am",
"C)9 am",
"D)11 am"
] | A | Assume both trains meet after x hours after 7 am
Distance covered by train starting from P in x hours = 20x km
Distance covered by train starting from Q in (x-1) hours = 25(x-1)
Total distance = 110
=> 20x + 25(x-1) = 110
=> 45x = 135
