A wheel rotates 10 times every minute and moves 20 cm during each rotation. How many metres does
     the wheel move in one hour?

      a) 6 metre        b)12 metre      c) 120 metre    d) 1200 metre
























Expl : Number of times wheel moves in 1 hour = 10 * 60 = 600

      :. Distance moves = (600 *20) cms = 12000 cms

      In metres  = 120 metre

Find the number of perfect squares in the given series 2013, 2020, 2027,.

Find the number of perfect squares in the given series 2013, 2020, 2027,................, 2300   (Hint 44^2=1936) a. 1   b. 2    c. 3   d. Can’t be determined Answer: a Explanation: The given series is an AP with common difference of 7. So the terms in the above series are in the form of 2013 + 7k.  We have to find the perfect squares in this format in the given series. Given that 44^2 = 1936. Shortcut: To find the next perfect square, add 45th odd number to 44^2. So 45^2 = 1936 + (2 x 45 -1) = 2025 46^2 = 2025 + (2 x 46 - 1) = 2116 47^2 = 2116 + (2 x 47 - 1) = 2209 Now subtract 2013 from the above numbers and divide by 7. Only 2209 is in the format of 2013 + 7k.  One number satisfies.
