To train starting at the same time from two station to 50 km apart and going in opposite directions cross each other at a distance of 170 km from one to two of the station. What is the ratio of their speeds?

In same time to cover 170 km at a kilometre respectively.

For the same time speed and distance is inversely proportional.

Suresh of the speed=17:80=17:8

The average of 5 quantities is 6. The average of 3 of them is 8. What is the average of the remaining two numbers?

The average of 5 quantities is 6.

Therefore, the sum of the 5 quantities is 5 *6 = 30.

The average of the 3 of these 5 quantities is 8.

Therefore, the sum of these 3 quantities = 3*8 = 24

The sum of the remaining two quantities = 30 - 24 = 6.

Average of these two quantities = 6 / 2 = 3.

In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

ab _ bcbca _ _ c _ bab

The series is abcbc / bcaca / cabab. Thus, the series consists of three sequences. The first sequence begins with a, the second with b and the third with c. Each sequence consists of a letter followed by other two letters repeated twice.

A man has a daughter and a son. The son is is three years older than the daughter. In one year the man will be six time as old as the daughter is now. In ten years the man will be fourteen years older than the combined ages of his children at that time. what is the man's present age?

Let's the age of daughter=x

age f son = x+3

age of father now=6x-1

condition:

M+0={(S+D)+ 10}+14]

6x-1=[{(x+3)+10}+14]

4x=28

x=7

Father's age=(6x-7)-1=41

In my row in the theatre the seats are numbered consecutively from T1 to T50. I am sitting in seat T17 and you are sitting in seat T39. How many seats are there between us?

The seats between us are numbered from T18 up to T38. So the seats between us are the 38 seats from T1 up to T38, other than the 17 seats from T1 up to T17. So there are 38 âˆ’ 17 = 21 seats.

.
The average of 5 consecutive even numbers is 34. What is the difference between the highest and lowest number.

Let's 5 consecutive even numbers are:

2, 4, 6, 8, 10.

Lowest term is 2 and highest is 10

10 - 2 = 8

So, difference of 8 will remain the same in the consecutive series numbers.
