Set a three-way ratio, choose which kind of clue you have been given, and set its amount. The walkthrough counts the parts, translates the clue, divides once, multiplies out all three shares and the total, checks the clue and the ratio, and then shows what three other clues would have been worth on the same split.
4 : 5 : 7, and C gets ₹1,200 more than A
3 parts · ₹400 a part · total ₹6,400
Switch between the difference clue at ₹1,200 and the pair clue at ₹3,600 on the same 4 : 5 : 7 ratio — two completely different sentences, the same ₹400 a part, the same answer.
