Find the missing numbers in the following proportions in the table given below. S.No. Proportion Product of extremes Product of means (i) 1 : 2 : : 4 : 8

The given proportion is: 1 : 2 : : 4 : 8 First term = 1 Second term = 2 Third term = 4 Fourth term = 8 First term and fourth term are called extremes and second and third terms are called means. Hence, Product of extremes = 1 × 8 = 8 Product of means = 2 × 4 = 8 Thus, S.No. Proportion Product of extremes Product of means (i) 1 : 2 : : 4 : 8 8 8

Find the missing numbers in the following proportions in the table given below. S.No. Proportion Product of extremes Product of means (ii) 5 : 6 : : 75 : 90

The given proportion is: 5 : 6 : : 75 : 90 First term = 5 Second term = 6 Third term = 75 Fourth term = 90 First term and fourth term are called extremes and second and third terms are called means. Hence, Product of extremes = 5 × 90 = 450 Product of means = 6 × 75 = 450 Thus, S.No. Proportion Product of extremes Product of means (ii) 5 : 6 : : 75 : 90 450 450

Find the missing numbers in the following proportions in the table given below. S.No. Proportion Product of extremes Product of means (iii) 3 : 4 : : 24 : 32

The given proportion is: 3 : 4 : : 24 : 32 First term = 3 Second term = 4 Third term = 24 Fourth term = 32 First term and fourth term are called extremes and second and third terms are called means. Hence, Product of extremes = 3 × 32 = 96 Product of means = 4 × 24 = 96 Thus, S.No. Proportion Product of extremes Product of means (iii) 3 : 4 : : 24 : 32 96 96
