Question
The current average age of students in a class is 24
years. What will the average age of the students be in 6 years?Solution
If all the terms increases by a number, say 'x', then the average also increases by 'x'. So, the average age of the class 6 years from now = 24 + 6 = 30 years
(√ 121 x 41) + (3√343 x √289 ) = ? x 19  Â

7, 8, 12, 21, 37, ?
Evaluate: 72 ÷ 6 × (5 + 1) − 8² + 10
What will come in the place of question mark (?) in the given expression?
(30 × 5 + 20) × 2 = ?
What will come in the place of question mark (?) in the given expression?
737 + 149 - ?²- 367 = 14 X 25(√ 1444 ÷ 5) × 3.25 = ?
522 + 160% of 80 - 130 = ? X 13Â
54% of 250 = 6 × 21 + √?
300% of (3341 – 471) = ? × (√4225/195)
