Question

The cost of 8A is equal to the cost of 50B. The cost of 19C is 456. The cost of B is twice the cost of 2C. What is the total cost of 3A and 4B together?

• A. 2184
• B. 2022
• C. 2080
• D. 1996

Answer 1

Answer:

A. 2184

CP of 8A= CP of 50B =>

A/B=50/8

A : B= 50:8

=>25:4

Let CP of A is 25x and CP of B is 4x

19C = 456

=> C=24

CP of B=2 times the CP of 2C=$3\times{2}\times{24}$=96

CP of B = 4x=96

X= 24

CP of A = 25x $=25\times{24}=600$

$3A +4B=3\times{600}+4\times{96}=2184$
