Too many errors ...
Reviewed in India on 18 October 2019
Ordered it a month before my IBPS PO mains exam in hope of practicing some advance DI (like funnel, box chart and scatter chart asked in SBI po) but got disappointed. Lots of pre exam stuff bundled into it.
Also, there are too many errors in the questions asked or in data given for eg. page 299 solution of question 15 is given wrong and in question 16 data given in question is wrong.
Likewise there are other questions which contain errors.
So final verdict. You can buy the books if you want to practice for prelims and are new to data interpretation. There are DI for mains level but not too many.
Price is not justified, is kept too high at ₹422 given the quality of the book and errors in it.
