Q17) since the track is a circular track ,A and B will meet every 50 seconds.i.e.,100/(10-8).
since it is a multiple of 50 they will be meeting at the starting point every 50 seconds.if you multiply 15*50 you will get 750 and after the second 50 it will be 1500.
all of them wil meet at the starting point after 100s

20)
if G Completes the work in 5 days den his son will complete n 25 days according to the question
so efficiency of G/efficiency of son= 1/5
let son complete the work in x days then G will complete the work in x-40 days
efficiency of G/efficiency of son=1/5=(x-40)/x
on solving
x=50 and x-40=10
now one day work of G +one days work of his son =1/10 +1/50=3/25
so both will complete the work in 25/3 days
