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.

Then, monthly bill = 10000PQ.
Now,
⇒ Price of tea = 120P (After 20% increase)
⇒ Monthly bill = 11000PQ (after 10% increase)
Then, consumption = 11000PQ/120P = 1100Q/12 = 91.67Q

Karan 7 years ago

8 years

Present age of Kapil = 5+8= 13 years
Kapil's age after 6 years = 19 years
Father's age after 6 years = 19*2=38 years
Present age of father = 38-6= 32 years
Romila's present age = 32/4= 8 years

In a consumer preferences survey, 20% respondents opted for product A, whereas 60% opted for product B. The remaining 20% individuals were undecided.
Difference in % age of those who opted for product B and those who were undecided = 40% of total
40% of total =720
Total individuals = 720/0.4 =1800

sohan takes twice as much time as mohan to complete a work and rohan does in it the same time as sohan and mohan together. if all of them working together can finish the work in 6 days , then find the time taken by each of then separately.

Suppose Sohan completes 1 unit of work in one day, then
Mohan completes 2 units of work in one day and
Rohan completes 3 units of work in 1 day.
All three together complete 6 units of work in 1 day.
All three together complete 36 units of work in 6 days.
Hence total work involves 36 units of work.
So sohan independently takes 36 days to complete work.
So Mohan independently takes 18 days to complete work.
So Rohan independently takes 12 days to complete work.

If cost price of one instrument is x, then CP of other instrument is 8000-x.
As per given condition,
1.4x= (8000-x)*0.6
x= Rs. 2400
Hence CP of two instruments are Rs 2400 and Rs. 5600.

It will never be empty.
Speed of filling by A and B pipes is greater than speed of pipe c to empty the cistern.
Further pipes A and B are opened before pipe C.
