Question
The HCF of two 3 digit numbers is 17, and their LCM is
1224. Calculate the difference between the two numbers.Solution
ATQ,
Let the numbers be ‘17x’ and ‘17y’ -------- {Where ‘x’ and ‘y’ should be co-prime number } ATQ, 17xy = 1224 Or, xy = 72 Only possible value of ‘x’ and ‘y’ is 8 and 9. So, the two numbers can be 136 (17 × 8) and 153 (17 × 9) Required dierence = 153 – 136 = 17
29.88% of 3599.90 + 5/12 of 2399.81 – 34.81% of 1200.18 = ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
59.978% of 800.315 - 229.95 = ? - 24.95% of 200.15
(`sqrt(224.95)` `xx` `sqrt(440.89)` ) + (`sqrt(783.82)` `xx` `sqrt(440.87)` ) = ? + 150.03% of 120.33 - 139.86% of 1249.88
