Question

4. A and B are given pens in the ratio 6:7. B and C are given pens in the ratio 14:15.
Find the ratio of pens given to A and C.
b. If the total number of pens given to A and C is 36, find the ratio of the number of pens A. B
and C gets.
a.​

Answer 1

The ratio between A and C can be easily calculated

by multiplying the two ratios as B and B cancell each other and we are left with A/C which cokes out as 4:5

now for finding A:B:C

take LCM of 7 and 14 which comes out as

14

so multiply 2 to the ratio A/B

we get 12:14 and B/C is 14:15

so A:B:C::12:14:15

Answer 2

Answer:

a. 4:5 b. A:B:C = 12:14:15
