Answer: 3 : 10
Explanation Given x:y = 3:4 and y:z = 2:5. To find x:z, we need to make y's ratio the same in both. y:z = 2:5 = 4:10 (multiply both parts by 2) Now, x:y = 3:4 and y:z = 4:10 So, x:z = 3:10 .
Answer: 3:2

Answer: 20000
Explanation For distribution between A & B the proportion has to be 2:3 Thus when A gets 2 units, B gets 3 units So A gets ₹20/- & B gets ₹30/- Distribution between B & C has to be 2:3 If ₹30 is 2, then 3 has to be ₹45/- So ₹ 95,000/- to be divided between A, B & C shall have to be in the proportion of 20:30:45 Thus A gets ₹20′000 /- B gets₹30′000/- and C gets ₹45000/-
