A traveler walks a certain distance

Ans:15km
solution:
speed(s)*time(t)=distance(d)
walked 1/2km with time 4/5
(s+0.5)((4/5)t)=d --->(1)
1/2km an hour slow, walked 2and half hr long
(s-0.5)(t+2.5)=d ----->(2)
solving (1) & (2)
we get s=2
t=7.5
d=2*7.5=15kmAkshujain

D = 15 kmsx = speed in km/hry = time takend / x = y - eq1d / x + .5 = (4/5)*y - eq 2d / x - .5 = 2.5 + y - eq 3 solving these three equation we get d = 15 x = 2 y = 7.5

A sum of money is divided among A, B and C such that for each rupee A gets, B gets 65paise and C gets 35paise. If C's share is Rs.560, the sum is … ?

Let x = rupees divided among b and cGiven x * 35/100=560x*65/100=560*65/35=> x = 10401040+ 560 = 1600and from the question we can say that a gets double of share which b and c together gets=> a's share is 3200

C's share = 560Â which is 35/200 of total sum.Total sum be x (35/200) * x =560x=3200 Rs.
