When Chinmay visited chowpati at Mumbai on a holiday, he observed that the ratio of North Indian food stalls to South Indian food stalls is 5 : 4. If the total number of food stalls is 117, find the number of each type of food stalls.
65 North Indian and 52 South Indian food stalls
Total ratio = 5 + 4 = 9. Each part = 117/9 = 13. North Indian = 5×13 = 65. South Indian = 4×13 = 52.
