Detailed Solution

Given:

Share of A = Rs 800

Calculation:

A ∶ B = 4 ∶ 5 ----(1)

And, B ∶ C = 2 ∶ 3 ----(2)

Multiplying eq (1) with 2

A ∶ B = 8 ∶ 10

Multiplying eq (2) with 5

B ∶ C = 10 ∶ 15

Now, A ∶ B ∶ C = 8 ∶ 10 ∶ 15

Let A, B, C be 8x, 10x, 15x respectively

Now, According to the question

8x = 800

⇒ x = 100

Total Money = 8x + 10x + 15x = 33x = 3300

∴ The total money among A, B and C is Rs 3300

Answer 2

let b has x amount of money.

then, 6:7::150:x

= 6/7=150/x

= 6x=7×150

= 6x= 1050

= x= 1050/6=175. ans.
