Question

Kindly answer the 11th question

Answer 1

Answer:

d) 8 : 6 : 10 : 9

Step-by-step explanation:

A:B = 1/2 : 3/8    i.e., A/B = 1/2 / 3/8 = 1/2 * 8/3 = 4/3    ........(i)

B:C = 1/3 : 5/9    i.e., B/C = 1/3 / 5/9 = 1/3 * 9/5 = 3/5   ........(ii)

C:D = 5/6:3/4     i.e., C/D = 5/6/4/3 = 5/6 * 3/4 = 10/9  .......(iii)

Now, A:B *2 = 8:6  ; B:C *2 = 6:10  ; C:D = 10/9

Therefore, A:B:C:D = 8:6:10:9
