1. Suppose the smaller number is x. Since the larger number is 10 more than the smaller number, it becomes x plus 10. According to the question, the sum of the two numbers is 64. Therefore, we form the equation x plus x plus 10 equals 64. This simplifies to 2x plus 10 equals 64. Subtracting 10 gives 2xRead more

    Suppose the smaller number is x. Since the larger number is 10 more than the smaller number, it becomes x plus 10. According to the question, the sum of the two numbers is 64. Therefore, we form the equation x plus x plus 10 equals 64. This simplifies to 2x plus 10 equals 64. Subtracting 10 gives 2x equals 54 and dividing by 2 gives x equals 27. Hence, the two numbers are 27 and 37.

  2. The chess club charges a fixed joining fee of 200 rupees. In addition, the player must pay 50 rupees for every match played. If the number of matches played is represented by m, then the total amount paid can be written as 200 plus 50m. This is a linear polynomial because the highest power of the vaRead more

    The chess club charges a fixed joining fee of 200 rupees. In addition, the player must pay 50 rupees for every match played. If the number of matches played is represented by m, then the total amount paid can be written as 200 plus 50m. This is a linear polynomial because the highest power of the variable m is 1. The amount paid increases regularly by 50 rupees whenever one more match is played.

  3. Assume Salil’s present age is x years. Since his mother is three times his age, her present age is 3x years. After 5 years, Salil’s age will become x plus 5 and his mother’s age will become 3x plus 5. According to the question, their total age after 5 years will be 70 years. Therefore, x plus 5 plusRead more

    Assume Salil’s present age is x years. Since his mother is three times his age, her present age is 3x years. After 5 years, Salil’s age will become x plus 5 and his mother’s age will become 3x plus 5. According to the question, their total age after 5 years will be 70 years. Therefore, x plus 5 plus 3x plus 5 equals 70. Solving gives x equal to 15. Hence, Salil is 15 years old and his mother is 45 years old.

  4. Since the ratio of the two integers is 2:5, let the integers be 2x and 5x. The difference between the larger and smaller integer is 63. Therefore, we form the equation 5x minus 2x equals 63. This simplifies to 3x equals 63. Dividing both sides by 3, we get x equal to 21. Substituting the value of x,Read more

This simplifies to 3x equals 63. Dividing both sides by 3, we get x equal to 21. Substituting the value of x, the two integers become 2 multiplied by 21 and 5 multiplied by 21. Hence, the integers are 42 and 105.

  5. Suppose Ruby has x five-rupee coins. Since she has three times as many two-rupee coins, the number of two-rupee coins becomes 3x. The total value of five-rupee coins is 5x rupees and the total value of two-rupee coins is 2 multiplied by 3x, which equals 6x rupees. Therefore, the total amount is 5x pRead more

    Suppose Ruby has x five-rupee coins. Since she has three times as many two-rupee coins, the number of two-rupee coins becomes 3x. The total value of five-rupee coins is 5x rupees and the total value of two-rupee coins is 2 multiplied by 3x, which equals 6x rupees. Therefore, the total amount is 5x plus 6x equals 88. Solving gives 11x equals 88, so x equals 8. Hence, Ruby has 8 five-rupee coins and 24 two-rupee coins.
