please solve this forex's question:-
Rs./pound 75.31/75.33
pound/dollar .6391/.6398
dollar/yen .01048/.01052
The rate at which yen can be purchased will be?
I took coaching from Rajesh Makkar sir...his approach for this type of ques is to multiply down .i.e.
Rs./yen=75.31*.6391*.01048/75.33*.6398*.01052
one of my frnd is studying from rajiv singh sir's cd..according to rajiv singh sir this short cut method should not be followed in exams..so guys pls tell me that rajesh makkar sir's approach is right or wrong???
