Mathematics / Reasoning
Percentage change = (new − old)/old × 100; successive changes of a% and b% give a net change of a + b + ab/100 percent.
Simple interest = P × R × T / 100; compound interest = P(1 + R/100)^T − P. For two years, CI − SI = P(R/100)².
Speed = distance/time; to convert km/h to m/s multiply by 5/18, and m/s to km/h multiply by 18/5.
Average = sum of observations / number of observations; if every value is increased by k, the average increases by k.
Ratio and proportion: if a:b = c:d then ad = bc; to divide a sum S in ratio a:b:c, the shares are S×a/(a+b+c), and so on.
Number series and coding-decoding: check differences, then ratios, then squares/cubes; in letter coding, fix the alphabet position (A=1 … Z=26) and the shift.
Blood relations and direction sense: draw a diagram; for directions, a left turn from North gives West, and a right turn from North gives East.
Permutation and combination: nPr = n!/(n−r)! for ordered arrangements; nCr = n!/[r!(n−r)!] for selections; probability = favourable outcomes / total outcomes.
