Question
The score of Riya is 30% more than that of Sneha. The score
of Tina is 100 more than the difference between Riya and Sneha. If Tina got 220 marks, find the marks scored by Riya.Solution
ATQ,
Let the marks obtained by Sneha be ‘x’.
So, marks obtained by Riya = 1.30x
According to question,
(1.30x – x) + 100 = 220
0.30x = 220 – 100
0.30x = 120
x = 120 / 0.30
x = 400
Therefore, marks obtained by Riya = 1.30 × 400 = 520 marks
