NCERT Solutions Class 8 Mathematics Chapter – 13 (Direct and Inverse Proportions) The NCERT Solutions in English Language for Class 8 Mathematics Chapter – 13 Direct and Inverse Proportions Exercise 13.1 has been provided here to help the students in solving the questions from this exercise. Chapter 13: Direct and Indirect Proportions • Exercise – 13.1 1. Following are the car parking charges near a railway station upto: 4 hours Rs.60 8 hours Rs.100 12 hours Rs.140 24 hours Rs.180 Check if the parking charges are in direct proportion to the parking time. Solution –Let’s find the parking charge for 1 hour in all the four cases shown below: 60/4 = 15/1 = ₹15 100/8 = 25/2 = ₹12.5 140/12 = 35/3 = ₹11.67 180/24 = 15/2 = ₹7.50 We see that the 1 hour charge in all the four cases shown below is not equal. Thus, the parking charges are not in direct proportion. 2. A mixture of paint is prepared by mixing 1 part of red pigments with 8 parts of base. In the following table, find the parts of base that need to be added. Solution – Let the ratio of parts of red pigment and parts of base be . Case 1: Here, a 1 = 1, b 1 = 8 = = k (say) Case 2: When a 2 = 4 , b 2 = ? k = b 2 = = = 4 × 8 = 32 Case 3: When a 3 = 7 , b 3 = ? k = b 3 = = = 7 × 8 = 56 Case 4: When a 4 = 12 , b 4 =? k = b 4 = = = 12 × 8 = 96 Case 5: When a 5 = 20 , b 5 = ? k = b 5 = = = 20 × 8 = 160 Combine results for all the cases, we have Parts of red pigment 1 4 7 12 20 Parts of Base 8 32 56 96 160 3.
