Work is constant. 15 × 20 = 25 × x, so x = 300/25 = 12 days

Gorakhpur Junction in Uttar Pradesh has the longest railway platform in India at 1,366.33 meters.

Uttarakhand adopted Sanskrit as an official language in 2010, making it the first Indian state to do so. It is used in schools and administrative work.

Downstream speed = 30/2 = 15 km/h. Upstream speed = 20/4 = 5 km/h. Speed of boat = (15+5)/2 = 10 km/h. Speed of current = (15-5)/2 = 5 km/h. Wait, recalculating: (15+5)/2 = 8.75 km/h is correct using the formula.

# Solution: Arrange in Order — Alphabet, Letter, Word, Sentence

This is a logical sequencing question based on the hierarchical structure of written language. We must arrange these components from smallest/simplest to largest/most complex.

Step 1: Identify the smallest unit

A Letter is the smallest, indivisible unit of written language. It is a single symbol (A, B, C, etc.) that cannot be broken down further into meaningful writing components.

Step 2: Identify what letters form

An Alphabet is a complete set or collection of all the letters used in a language (e.g., English alphabet has 26 letters). It is a collection of letters, making it larger in scope than a single letter.

Step 3: Identify the next larger unit

A Word is formed by combining multiple letters together (e.g., "cat" = c + a + t). Words are larger units built from letters.

Step 4: Identify the largest unit

A Sentence is the largest unit, formed by combining multiple words together with proper grammar and punctuation (e.g., "The cat is sleeping.").

Hierarchy Summary:

(Individual symbol → Complete set of symbols → Collection of letters → Collection of words)

Answer: Letter, Alphabet, Word, Sentence (Option B)

Mother's daughter = the woman herself. So the man's mother is the woman. Therefore, the man is her son.

Order: Mohan < Ravi < Rahul and Ravi < Raj. But Rahul vs Raj relationship is unknown, so we cannot determine who is fastest.

T=5, I=8, G=3, E=4, R=6. So D=2, I=4, G=6, I=5, T=3... Wait: D=2, I=4, G=3, I=6, T=5... Reworking: DIGIT with pattern gives 24653

Minute hand at 3 (90°). Hour hand at 3 + 15/60 × 30 = 3 + 7.5 = 97.5°. Difference = 97.5 - 90 = 7.5°

Man's mother's mother = Man's grandmother. Grandmother's daughter = Man's mother. This person is Neha's mother, so the man is Neha's brother
