Question

The ratio of marks obtained by Amal, Bimal and Komal in an examination is ` 12 : 8 : 15`. Find the marks obtained by Bimal and Komal, if Amal scored 15 marks less than that of Komal.

Answer 1

Let the marks scored by Amal, Bimal and komal by 12x, 8x and 15x , respectively.
Given that Amal scored 15 marks less than that of Komal.
` rArr 12 x = 15x - 15`
` rArr 3x = 15`
` rArr x = 5`.
`:.` Marks scored by Bimal = 8x = 8(5) = 40.
Marks scored by Komal = 15x = 15(5) = 75.
