A) 24, Rs.1380
B) 48, Rs. 1680
C) 48, Rs.1285
D) 24, Rs.2000
Correct Answer: B
Solution :
Number of tiles required = \[\frac{Area\text{ }of\text{ }rectangular\text{ }floor}{Area\text{ }of\text{ }each\text{ }tile}\] \[=\frac{200\times 150}{25\times 25}=48\] Cost of 12 tiles =Rs. 420 So, cost of 1 tile \[=Rs.\,\frac{420}{12}=Rs.35\] Cost of 48 tiles \[=Rs.(35\times 48)=Rs.1680\]You need to login to perform this action.
