The ratio of the marks obtained by Priya, Neha, and Riya
is 4:7:9 respectively. Sheetal scored 5 marks less than Neha. If the difference between Riya’s and Priya’s marks is 40 marks, what is the ratio of Neha’s marks to Sheetal’s marks?Solution
Let marks be 4x, 7x, and 9x respectively.
Sheetal’s marks = 7x - 5
ATQ,
9x - 4x = 40
Or, 5x = 40
Or, x = 8
Neha = 7 × 8 = 56
Sheetal = 56 - 5 = 51
Required ratio = 56:51
