Question
Consider the following statement 23716 is a
perfect square number? Statement I – The number which is ending with 2, 3, 7 and 8 cannot be perfect sq. Statement II – Last two digits must be same as last two digit of square of 1 to 24.Solution
As we know that if a number is a perfect square then it must follow the properties , that is number should not ended with 2,3,7 and 8 and also two digits should be same as the last two digits of square of 1 to 24. So both are required to answer the following question.
- What will come in place of (?) in the given expression.
(18.5 Ă— 2) + (3.5 Ă— 4) = ? If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
40% of 50 + 50% of ? = 25% of 300 - 10% of 250
√10000 x √8100 - (50)² = √(?) + (80)²
1428 ÷ 17 = ? % of 120
- Identify x such that x% of 540 plus {1080 Ă· x of 9} Ă— 6 gives 162
Simplify the following expression:
Simplify the expression:
(9x² - 25) / (3x + 5)
135 Ă· 3 of 5 = ? - 112
