Answer 1

Answer:

The marks obtained by Karan is 55.

Step-by-step explanation:

Let the marks obtained by Karan be x.

The total marks obtained by three of them is given 140

It is said that Karan obtains 10 more marks than Bhavana

Karan=10+Bhavana

x=10+Bhavana

marks obtained by Bhavana=x-10

Isha is said to have obtained 5 less marks than Bhavana

isha=Bhavana-5

isha=x-10-5=x-15

Marks obtained by Isha =x-15

The total marks obtained by three of them =140

Karan+Isha+Bhavana=140

x+x-15+x-10=140

3x-25=140

3x=140+25

3x=165

x=55

Thus the marks obtained by Karan is 55.
