The ratio of number of students studying Arts, Commerce and Science in a College is 3 : 5 :8. What is the new ratio of the number of students studying Arts, Commerce and Science respectively if there is an increase of 20%, 40% and 25% in the number of students studying Arts, Commerce and Science? Choose the correct option
A) 18 : 35 : 50  B) 3 : 10 : 10  C) 4 : 8 : 5  D) 32 : 35 : 25  E) None of these
Suppose the number of students studying Arts, Commerce and Science be 3x, 5x and 8x respectively.   When their numbers are increased by 20%, 40% and 25% respectively the new ratio becomes   3x × 120% : 5x × 140% :   8x × 125% = 36 : 70 : 100   = 18 : 35 : 50   18 : 35 : 50nswer 18 : 35 : 50
