Hey guys,
I was trying to solve the DS questions in MGMAT 4th edition, guide 2, chapter 6 (page 89) and I was struggling to set up an equation for #77 in OG 12. I have gone through the book but it seems like, this guide did not cover on how to tackle such questions and writing equations for stmt 1 of #77....do you guys have any other source that could help me solve problems like this?
My suggestion will be to write down after reading the statements in the mathematical format. Just read one sentence at a time and write down into mathematical format. You will find it easy after solving few examples.
