About This Set
These 25 questions are at the level of a Tier 1 shift and are worded the way SSC writes them, most often as the value of an expression with four numbers or four ratios to choose from. As in the exam, the bulk is identities to simplify, a value worked out from a given condition, and complementary-angle sums and products; the traps are a minus sign outside the first quadrant, a maximum taken as instead of , and a ratio turned upside down at the last step. When all four options are numbers, putting into the expression often settles it. Take about 20 minutes; 20 or more right means Practice Set 3 is the next step.
