Question

14. IfA: B = 2: 3 and B : C = 4:5, find
(i) A:B:C
(ii) Divide₹ 2625 among A, B and C in the proportion as obtained above
​

Answer 1

Answer:

(i) a : b : c = 8 : 12 : 15

(ii) a = ₹600, b = ₹900, c = ₹1125

Step-by-step explanation:

a : b = 2 : 3

b : c = 4 : 5

now

a : b : c = ?

a : b : c

2 : 3

4 : 5

**we put the blank place with the same number in it right or left side & multiply from up to down to get the ratio, like this =>

=> a : b : c

2 : 3 : 3

4 : 4 : 5

*****************

8 : 12 : 15

so

a : b : c = 8 : 12 : 15

shares =>

sum of ratio = 8+12+15 = 35

amount = ₹2625

a = 2625 × 8/35 = 75 × 8 = ₹600

b = 2625 × 12/35 = 75 × 12 = ₹900

c = 2625 × 15/25 = 75 × 15 = ₹1125
