Answer 1

Answer:

Explanation:

total marks= 442

lets kamla's marks be= y

shantas marks= y-10

shradhas marks= y+10

ATQ:

442= y+ (y-10) + (y+10)

     =  y+y-10+y+10

      = y+y+y-10+10

442= 3y

y= 442/3

Answer 2

Answer:

139

Explanation:

Let the mark of Kamala be x

Kamala=x.

shantha=x-10

Sharada=x+5

x+(x-10)+(x+5)=442

3x-5=442

3x=442+5

x=447/3=149

now to find mark of shantha,

shanta=x-10

=>149-10

=139
