A) \[Rs.\text{ }400\text{ }k\]
B) \[Rs.\text{ }530.75\text{ }k\]
C) \[Rs.~538.75\text{ }k\]
D) \[Rs.\text{ }600\text{ }k\]
Correct Answer: C
Solution :
Cost of 1 vacuum cleaner set \[=Rs.\,154.25\,k\] \[\therefore \] Cost of 3 vacuum cleaner sets \[=Rs.\,(3\times 154.25\,k)\] Cost of 1 additional pipe \[=Rs.15.20\,k\] \[\therefore \] Cost of 5 additional pipes \[=Rs.\,(5\times 15.2\,k)=Rs.\,76\,k\] So total cost \[=Rs.(462.75k+76k)=Rs.\,538.75k\]
