The question asks “What is the exchange rate of rupee to ringit” which I understand as you want to exchange the rupees you have for a number of ringits, however the “correct” answer states “the number of Rupees you could buy for every ringit”, is this not “ringit to rupee” IE you’re exchanging ringit’s FOR rupees when the question asks rupees FOR ringits. The correct answer should be 1/13=0.077.
