  • Question 3
    1 / -0

    A company's expense on petrol and food per employee in a month is Rs. 5000. If there are 2 × 105 employees in the company, then what is the total expense of the company on petrol and food per month?

    Solution

    Expense per employee = Rs. 5000 = Rs. 5 × 103

    Total number of employees = 2 × 105

    Total expense of the company per month = Rs. 5 × 103 × 2 × 105 = Rs. 10 × 108

     

  • Question 4
    1 / -0

    The highest amount of money in the Reserve Bank in a certain year was approximately Rs. 3.7856 × 1020 and the lowest amount of money in the bank the same year was approximately Rs. 2.8566 × 1020. What was the average amount of money in the Reserve Bank that year?

    Solution

    Highest amount of money = Rs. 3.7856 × 1020

    Lowest amount of money = Rs. 2.8566 × 1020

    Average amount of money = Rs. ((3.7856 + 2.8566 )× 1020) ÷ 2

    = Rs. (6.6422 × 1020 ÷ 2 )

    = Rs. 3.3211 × 1020

     

  • Question 5
    1 / -0

    The distance between the Earth and the Moon is 4 x 105 km and the distance between the Earth and the Sun is 150 x 106 km. Find the distance between the Moon and the Sun if all of them are in a straight line, given that Moon lies between the Earth and the Sun.

    Solution

    Moon lies between Earth and Sun. So, the distance

    = 150 x 106 - 4 x 105 km

    = 1500 x 105 - 4 x 105 km

    = 1496 x 105 km
