Let the length of the train be x meters and its speed be y m/sec.
They, x / y = 15 => y = x/15
x + 100 / 25 = x / 15
x = 150 m. | AquaRat_train |
A letter lock consists of three rings each marked with eight different letters. The number of distinct unsuccessful attempts to open the lock is at the most? | [
"176",
"511",
"172",

] | B | Since each ring consists of eight different letters, the total number of attempts possible with the three rings is
= 8 * 8 * 8 = 512. Of these attempts, one of them is a successful attempt.
Maximum number of unsuccessful attempts

The odd numbers do not have 2 as a factor and there are 100 odd numbers from 1 to 200.
We then need to eliminate the 20 numbers that end with 5, that is 5, 15, 25,...,195.
There are a total of 100 - 20 = 80 such numbers between 1 and 200.

"130 kms.",
"110 kms.",
"120 kms.",
"100 kms."

If distance between B and R is 120 kms,
Time taken by trains before collision = 120/(60+60)=1 hr
Distance traveled by bird in 1 hr = 120 kms.
so The distance traveled by the bird before it is killed = 120 kms.
