Question
The marks scored by Neha are 50% more than those of Priya.
The marks obtained by Sia are 160 more than the difference between Neha and Priya. If Sia got 310 marks, find the marks scored by Neha.Solution
ATQ,
Let the marks obtained by Priya be βxβ.
So, marks obtained by Neha = 1.50x
According to question,
(1.50x β x) + 160 = 310
0.50x = 310 β 160
0.50x = 150
x = 150 / 0.50
x = 300
Therefore, marks obtained by Neha = 1.50 Γ 300 = 450 marks
