Given: Ratio of Vijay and Amith=4:5

Ratio of Amith and Abhishek=3:2

Find: Calculate the ratio of marks obtained by Vijay and Abhishek.

Solution: Ratio of Vijay and Amith=4:5

Ratio of Amith and Abhishek=3:2

Combining ratio of Vijay, Amith and Abhishek=4:5:5×(3:3:2)

                                                                            = 4x3:5x3:5x2

                                                                            = 12:15:10

Ratio of Vijay and Abhishek=12:10

                                             =6:5

Final answer: B) 6:5.
