Reply Like? Yes | No

Dr.Dipin Singh 7 years ago

Ratio of mixture should be 1:5.

CP of 6 kg mixture = (50*1+60*5)/6 = Rs 350/6
SP of 1 kg mixture for 20% profit = 350*1.2/6 = 35*12/6= rs 70

Sudipta Sikder 7 years ago

Cost Price of 1 kg mixture = (100/100+20)*70 = 175/3
now by rule of alligation ratio will be
(175/3 - 5):(60-175/3)
=1:5

a) 100km
b) 35km
c) 150km
d) 140km

Reply Like? Yes | No

Devendra Marghade 7 years ago

d) 140km

Let after time of 't' hrs both train meets, then
Distance covered by train leaving at 6.30 am at 30 kmph = Distance covered by train leaving at 7.40 am at 40 kmph.
=> (1 hr 10 min + t)*30 = t*40
=> (7/6 + t)*30 = t*40
=> t = 7/2 or 3.5 hrs i.e. both train meets after 3 hr & 30 min.
Hence distance covered from A is (7/6 + t)*30 or t*40 = 140 km.

Ans.15/16.

Explanation: Because there 2 chances. And 4 digits are to be used. So total no. Of possible outcomes is 2^6=16.
In 2 chances, except 1111, every outcome will have ≥ 1 zero's.
So P(0)= 16-1/16
= 15/16.
