The Price of 357 apples is Rs.2499. What will be the price of 49 dozens of such apples?

 If 96 is divided into  four parts proportional to  5, 7, 4, 8 then the smallest part is :

 a) 16        b)14     c)20     d) 18

















. Expl : More apples, more cost(Direct)

      357 *588 : : 2499 : x

      x = (588*2499)/357 = 4116


















Expl : Given ratio = 5 : 7  : 4  :  8 , sum of ratio = 24

     :. The smallest part = (96 *4/24) = 16

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.
