Question

7)A and B are given pens in the ratio 6:7. B and C are given pens in

the ratio 14:15

a) find the ratio of pens given to A and C

b) If the total no. of pens given to A and Cis36,find the ratio of

no. of pens A,B​

Answer 1

Answer:

a. 4 : 5

b. no of pens with A are 16 , with C are 20 and with B are 56/3.

Step-by-step explanation:

The ratio of A and B is 6 : 7 so we can wrote this even as 12 : 14 by multiplying with 2 which will have no effect in the ratio. So now we can compare among A, B and C as 12 : 14 : 15.

Finally the ratio between A and C is 12 : 15 which can be deduced further to 4 : 5.

Now that we got the ration between A and C we can get the values of A and C as A=(4/9)*36 = 16 and C= (5/9)*36 = 20.

Using any one value of A or C we can get the value of B as B=(7/6)*16 = (56/3) .
