    What is the difference between 8 tens 24 tenths and 25 hundredths and 6 tens 28 tenths and 90 thousandths?
    Solution
    8 tens 24 tenths and 25 hundredths = = 80 + 2.4 + 0.25 = 82.65
    6 tens 28 tenths and 90 thousandths = = 60 + 2.8 + 0.09 = 62.89
    The difference between( 8 tens 24 tenths and 25 hundredths) and (6 tens 28 tenths and 90 thousandths) = 82.65 - 62.89 = 19.76

  • Question 7
    1 / -0
    What fraction of the given figure is unshaded?

    Solution
    We have to divide the shaded parts in halves. This is done because it is not possible to find the fraction without making equal parts as shown in the figure:

    So, total number of equal parts = 12
    Number of shaded parts = 4
    Number of unshaded parts = 8
    Fraction of the unshaded parts =

  • Question 23
    1 / -0
    Rohan and Abhinav together spent Rs. 150 at a movie theater, Abhinav and Feroz spent Rs. 343 together. If Abhinav spent of what Feroz spent, how much did Rohan spend?
    Solution
    We know that Abhinav spent of what Feroz spent.
    Money spent by Abhinav + Feroz = Rs. 343

    Therefore,
    money spent by Feroz + money spent by Feroz = Rs. 343
    money spent by Feroz = Rs. 343
    Money spent by Feroz = Rs. 343 ×
    Money spent by Feroz = Rs. 294
    Money spent by Abhinav = Rs. 343 - Rs. 294 = Rs. 49
    So, money spent by Rohan = Rs. 150 - Rs. 49 = Rs.101

    Solution
    (i) A = 359.48 - 343.68 = 15.8
    (ii) B = 23.62 + 4.9 = 28.52
    (iii) C = 14.49 - 4.43 = 10.06

    B x C - A = 28.52 x 10.06 - 15.8 = 271.1112
