Purple_Wizard, yes, the third part to the first question requires much more calculation than what would be expected. However, the first part that speaks of >15% can be scanned and answered.
@chetan2u - I couldn’t see the calculator when I was solving DI Qs, can you pls suggest where do I click to get it while practising in test mode?
Also, a lot of MSR / GI Qs have the calculator mentioned in the answers so how can we improve our accuracy with the calculator?
