Question
Statement: Should all the industries in big cities be
relocated at the outskirts of them in order to prevent industrial pollution. Arguments: 1) No, Transfer of industries is going to cost more. 2) Yes, The effects of industrial pollution are far reaching and liable to affect the eco-system for many years to come. Most industries require large amounts of water for their work. When involved in a series of processes, the water comes into contact with heavy metals, harmful chemicals, radioactive waste and even organic sludge. Each question given below consists of a statement, followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is.Solution
Argument I is weak and Argument II is strong because it clearly shows the impact of industrial pollution.

- 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:
