    If 578 and 245 are multiplied, from the product we get, a new number is formed using the unit digit and the tenth digit, then what is that number?

    Solutions

    578 = 172×2

    245 = 72 ×5

    To get one zero, we need a pair of 2 and 5, after that 289and 49, when they are multiplied we will get 1 as unit digit.

    Find the average of the following numbers 2095, 2089, 2091,2077, 2073 and 2097?

    Solutions

    Average can be found out by summing up all these numbers and dividing by 6.

    But here it may become tedious; here we have to adopt deviation method.

    Here we have to assume a number that is easier for calculation and assume it as average, and then we will calculate the deviation of each number from the assumed average and find the average of deviation and either add or subtract from the assumed average.

    Let us assume the average to be 2085, then

    Sum of the deviations = 10 + 4 + 6 – 8 – 12 + 12 = 12

    Average of deviation = 12/6 = 2

    Hence the average = 2085 + 2 = 2087

     

  • Question 10/10
    1 / -0

    The HCF and LCM of two numbers are 3780 and 113400, if one of the numbers is 7560, then find the other number?

    Solutions

    Product of the numbers is equal to the product of their HCF and LCM. Hence

    37840×113400 = 7560 × number2

    Number2 = 56700
