Hi Noman,

This question can be solved by TESTing VALUES.

IF...
Babu earns $100
Then....
Arif earns $130
Salek earns $160

We're asked to compare Salek's wages to Arif's wages (as a matter of percentage increase).

160/130 = 16/13 = a little more than 1.2

So Salek's wages are a little more than 20% greater than Arif's wages.

Final Answer: A
