Rahul's present age: In 4 years he will be 31, so currently 31 − 4 = 27 years.
Seema's present age: Rahul is 3 times as old as Seema, so Seema = 27 ÷ 3 = 9 years.
Laxmi's present age: Four years ago Rahul was 23 years (27 − 4), and Laxmi was twice that age = 46 years. Currently Laxmi = 46 + 4 = 50 years.

If + means ×, × means −, ÷ means + and − means ÷, then 175 − 25 ÷ 5 + 20 × 3 + 10 equals to:
Detailed Explanation:
Given substitutions: − means ÷, ÷ means +, + means ×, × means −
Original expression: 175 − 25 ÷ 5 + 20 × 3 + 10
After substitution: 175 ÷ 25 + 5 × 20 − 3 × 10
Apply BODMAS:
Division first: 175 ÷ 25 = 7
Multiplication: 5 × 20 = 100 and 3 × 10 = 30
Addition and subtraction: 7 + 100 − 30 = 77

Writing in Alphabetical order, which name of the following will appear in the last?
Detailed Explanation:
Alphabetical order is determined by comparing letters from left to right until a difference is found.
Comparing all four names: Mahendra and Mahinder start with "Ma", while Mohender and Mohinder start with "Mo". Since "o" comes after "a", the "Mo" names appear later.
Between Mohender and Mohinder: after the common prefix "Moh", we compare "e" vs "i". Since "i" comes after "e" in the alphabet, Mohinder appears last.
