What is the next number in this series?
6, 14, 36, 98, 276, ?

View AnswerDiscuss in Forum

     Answer & Explanation

Solution:
794

The nth term in the series is given by the sum of x^n for x in the range 1 to 3, i.e. 1^n + 2^n + 3^n.

Thus the first term is 1^1 + 2^1 + 3^1 = 1 + 2 + 3 = 6,
the second term is 1^2 + 2^2 + 3^2 = 1 + 4 + 9 = 14,

It was only a trick:
I borrowed my parents (Rs50 + Rs50 = Rs100).
I bought the jeans for Rs97 and i had Rs3 change.

and the change Rs3 also the borrowing money the jeans is Rs97
Total: Rs97 + Rs3(the change) = Rs100
The money that i used to buy the jeans all i borrowed.
Rs97 is the borrowing money, change: Rs3 also the borrowing money. Rs97 + Rs3 = Rs100

Solution:
Horse is carrying 5 boxes and the camel is carrying 7 boxes.

Let's assume that the horse was carrying H boxes and the camel was carrying C boxes.
C + 1 = 2 * (X-1)
C + 1 = 2H - 2
C = 2H - 3

Also,
C - 1 = H + 1
C = H + 2

=>
2H - 3 = H + 2
H = 5

=>
C = 7

Math Logic Puzzles 10 : Maths Classic Race Puzzle
Difficulty ★★★★☆        Popularity ★★★★☆

Lavesh, Bolt, and Lewis race each other in a 100 meters race. All of them run at a constant speed throughout the race.

Lavesh beats Bolt by 20 meters.
Bolt beats Lewis by 20 meters.

How many meters does Lavesh beat Lewis by ?

View AnswerDiscuss in Forum

     Answer & Explanation

Solution:
Lavesh beats Lewis by 36 meters.

It is tempting to guess that Lavesh beats Lewis by 40 meters, but when Lavesh finishes and is 20 meters ahead of Bolt, Bolt is NOT 20 meters ahead of Lewis (he's only 16 meters ahead), and it will take a couple more seconds before Bolt increases his lead over Lewis to 20 meters.

To figure out the answer, we let Lavesh's speed be A meter/second. So it takes him 100/A seconds to finish the race. At this point, we know that Bolt has run 80 meters (since Lavesh beats him by 20 meters). So Bolt runs 80 meters in 100/A seconds, meaning that he is running at a speed of (80/(100/A)) meters/second, or (8A/10) meters per second.

So we then know that it takes Bolt 100/(8A/10) seconds to finish the race, or 125/A seconds. At this point, we know that Lewis has run 80 meters (since Bolt beats him by 20 meters). So Lewis runs 80 meters in 125/A seconds, meaning that he is running at a speed of (80/(125/A)) meters/second, or 80A/125 meters per second.

Now that we know Lewis's speed, we just need to figure out how far he had run when Lavesh finished the race. Since Lavesh finished in 100/A seconds, we can determine that Lewis had run (100/A) * (80A/125) = 8000/125 = 64 meters when Lavesh finished the race. And so Lavesh beat him by (100 - 64) = 36 meters.
