Area= 1/2*height*base=10
1/2* ( y co-ordinates of C) * (AB) = 10
1/2* ( y co-ordinates of C)*5=10
( y co-ordinates of C)= 4
1. (0, 4) can be co-ordinates of C, y co-ordinates of C is equal to 4.
2. (2, 5) can't be the co-0rdinates of C as y co-ordinate of (2,5) is not equal to 4
3. (3, 4) can be the co-ordinates of C, y co-ordinates of C is equal to 4.
1/2* ( y co-ordinates of C) * (AB) = 10
1/2* ( y co-ordinates of C)*5=10

1. (0, 4) can be co-ordinates of C, y co-ordinates of C is equal to 4.
2. (2, 5) can't be the co-0rdinates of C as y co-ordinate of (2,5) is not equal to 4
3. (3, 4) can be the co-ordinates of C, y co-ordinates of C is equal to 4.

height of ∆ ; 1/2 * x*5= 10 ; 4
so option with y as 4 is answer
IMO D
