Find x in the following proportions:(i) 16: 18 = x: 96(ii) x: 92 = 87:

1.	Find x in the following proportions:(i) 16: 18 = x: 96(ii) x: 92 = 87: 116
Answer» (i) Given 16: 18 = x: 96 In proportion we know that product of extremes = product of means 16/18 = x/96 On cross multiplying x = (18 × 96)/ 16 x = 256/3 (ii) Given x: 92 = 87: 116 In proportion we know that product of extremes = product of means x/ 92 = 87/116 On cross multiplying x = (87 × 92)/ 116 x = 69

Find x in the following proportions:(i) 16: 18 = x: 96(ii) x: 92 = 87: 116

Answer»

(i) Given 16: 18 = x: 96

In proportion we know that product of extremes = product of means

16/18 = x/96

On cross multiplying

x = (18 × 96)/ 16

x = 256/3

(ii) Given x: 92 = 87: 116

In proportion we know that product of extremes = product of means

x/ 92 = 87/116

On cross multiplying

x = (87 × 92)/ 116

x = 69
