6.40 am ans
longitudinal difference=70W-10E=80
means destination is 80 degree West from start point
time difference=4min*longitudinal diff =4*80=320 min
for linear distance it reach at 2am+10 hr=12pm
but here 12pm - 320 min = 6.40 am

a:b = 3:5 = 24:40 (intentionally multiplied with 8)
b:c = 8:5 = 40:25 (intentionally multiplied with 5)

so a:b:c = 24:40:25

b has 40 parts out of 89 (i.e. 35 liters)

so b in liters = 35 * 40 / 89
= 15.73 liters

a:b:c=3*8 : 5*8 : 5*5 = 24:40:25
total 24+40+25=89 part =35 litres
so 40 part = 40*(35/89) =15.73 litres

Ans is 20
Let paul was x year old that time, then peter is 2x year old now.
Now if paul is y year old now, then peter was y year old that time.
Let time is t
So y+t=2x
x+t=y
Given 2x+y=35
By solving, peter's present age 2x=20 year

Other way- let peter's age p and paul's age q
p=2(q-(p-q))
And p+q=35
By solving
p=20 year
