Question

monthly income of A and B are in ratio 6:7 and those of B and C are in the ratio 7:9 if A earns rupees 36000 find the income of B and C

Answer 1

Answer:

The income of B and C are 42000 Rs. and 54000 Rs.

Step-by-step explanation:

Ratio of A , B , C is 6:7:9.

Let , A ears 6x , B earns 7x , C earns 9x Rs.

6x = 36000.

or , x = 6000.

So, B earns 7*6000 Rs. = 42000 Rs.

C earns 9*6000 Rs. = 54000 Rs.

The income of B and C are 42000 Rs. and 54000 Rs.

Answer 2

Answer:

The income of B = 42000 , and C = 54000

Step-by-step explanation:

Given :- A:b = 6:7  , B:C = 7:9 .

To find :- value of income of B and C .

Solution :-

Step 1) For A and B , let the common factor be x

therefore , the income of $A = 6x , B= 7x$

given that , income of A = 36000 ,

hence , $6x = 36000\\x = 36000/6 \\x = 6000$

therefore , income of B = $7x = 7*6000 = 42000$.

Step 2) In the case of B and  C ,

Let , y = common factor .

since the income of B = 42000 ,

$7y=42000 \\y = 42000/7 \\y = 6000$

Therefore , income of C = $9y = 9(6000) = 54000$

Hence the income of B = 42000 , and C = 54000
