Question

2)The teacher tells the class that the highest marks obtained by the students in her class is 9 more than thrice the lowest marks. If the highest score is 90, find the lowest score. ​

Answer 1

Answer:

Highest marks = 9 + (3 x lowest marks)

Step-by-step explanation:

Highest marks = 90 ( as mentioned in the question)

Let's consider lowest marks as x

90 = 9 + 3x

Transposing

3x = 90 - 9

3x = 81

x = 81/3

x = 27

Therefore the lowest marks scored are 27.
