Question
Anil has purchased two adjacent plots - one is in
rectangular shape and the other is in square shape and combines them to make a single new plot. The breadth of the rectangular plot is equal to the side of the square plot and the cost of fencing the new plot is ₹390 means (₹5/m). What will be the side of the square when the length of the rectangular plot is 15m.Solution
ATQ, we can say that  Given the Length of rectangular plot is = 15m  Breadth of rectangular plot = side of square plot = 'p'  Now, 2(p + 15) + 2p = 390/5  2p + 30 + 2p = 78  4p = 48  p = 12m

- The L.C.M and H.C.F of two numbers have a sum and difference of 440 and 120. If one number is 40, find the other.
The HCF of two numbers is 14. If their product is 5488, then how many such pairs exist?
If the sum of 2 numbers is 185, their LCM is 1700 and HCF is 5. Then the difference between 2 numbers is:
