A) \[36:65:47\]
B) \[65:25:80\]
C) \[35:47:90\]
D) \[36:65:90\]
Correct Answer: D
Solution :
Originally, let the number of seats for Mathematics, Physics and Biology be \[5x,7x\] and \[8x\] respectively. Number of increased seats are (\[120%\]of\[3x\]), (\[130%\]of\[5x\]) and (\[150%\]of\[6x\]). \[\Rightarrow \] \[\left( \frac{120}{100}\times \,3x \right)\], \[\left( \frac{130}{100}\,\,\,\,\,\,5x \right)\] and \[\left( \frac{150}{100}\,\,\,\,\,\,6x \right)\] \[\therefore \] The required ratio \[=36x:6.5x:9x\] \[\Rightarrow \] \[36:65:90.\]You need to login to perform this action.
