Towns A and B are 400 miles apart. If a train leaves A in the direction of B at 50 miles per hour, how long will it take before that train meets another train, going from B to A,
at a speed of 30 miles per hour?

Answers

from A :50/hour. *x(hour)
From B : 30/hour *x(hour)
50 *x +30 *x =400
80 *x=400
x=5(hour)
Then the train from A will make 50 *5=250 miles

What are permutation and combination?

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

The serial number on a bill consists of a letter followed by seven digits and then a letter.

A) Letters and digits cannot be repeated. Then the number of ways will be

⇒ 26 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 25

⇒ 39,31,20,000

B) Letters and digits can be repeated. Then the number of ways will be

⇒ 26 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 26

⇒ 6.76 × 10⁹

C) The letters are non-repeated consonants and the digits can be repeated.

⇒ (5 x 10⁷ x 5) + (21 x 10⁷ x 5) + (5 x 10⁷ x 21)

⇒ 0.25 × 10⁹ + 1.05 × 10⁹ + 1.05 × 10⁹

⇒ 2.35 × 10⁹
