63. A man walks at 40kmph and reaches the distance in 10 min less than that of usual. By walking at 60 kmph he reaches 10 minutes earlier. The distance covered by him is?
Answer:
Explanation:let x be distance in km, let t be usual time
given 40km/hr=40/60km/min=2/3km/min 10 min less t+10
given 60km/hr=60/60km/min=1km/min 10 min early t-10
since, speed=distance/time
2/3=x/t+10.......(1)
1=x/t-10.....(2)
divide (1) by (2)
2/3 = t-10/t+10 = t=50min
x=50-10=40km

65. Sneh's age is 1/6th of her father's age. Sneh's father's age will be twice of Vimal's age after 10 years. If Vimal's eighth birthday was celebrated two years before, what is Sneh's present age?
Answer:
Explanation:Vimal's age after 10 years = (8+2+10)years= 20 years.
Sneh's father age after 10 years = 40 years (Twice than Vimal's age after 10yr)
Sneh's father Present age = 30 years (40yrs -10yrs)
Therefore Sneh's age = (1/6 * 30)years= 5 years.
