1. Parag arrives at Pimpri Railway station from office every day at 6:00 p.m.(adsbygoogle = window.adsbygoogle || []).push({});

where Prajakta picks him up in the car to take him home. One day he arrives

at Pimpri one hour early and starts walking towards home. On the way he

meets Prajakta and they return home together in the car. If they arrive the

home 10 minutes earlier then what is the ratio of Parag's walking speed to

Prajakta's driving speed???

Work done by me on this question:

Let distance from station to home= d metres

Driving speed=v1 m/s

Walking speed=v2 m/s

Time taken by car usually=d/v1

according question (if x is the distance travelled by walking),

d/v1={(d-x)/v2}+(x/v1)+600

On solving,

{(d-x)/v1}-{(d-x)/v2}=600

But I cant find the ratio??????????????????????????????????

2.If a/(b+c) = b/(a+c) = c/(a+b) and a+b+c is not 0 then find value of each

ratio.

Work done:

The answer given in my book is -1. But I dont think that a+b+c will not be

equal to zero in that case???

This is all I could do. Please dont give me answers like show me your work etc. If you know it tell me otherwise dont.
