A) 48
B) 46
C) 42
D) 45
Average of A, B, C, D, E:
(A+B+C+D+E )/5 = 40
A+B+C+D+E = 200 —- ( i )
Average of A & B:
(A+B)/2 = 35 ⇒ A+B=70 —–( ii )
Average of C & D:
(C+D)/2= 42 ⇒ C+D=84 —–( iii )
Adding equation ( ii ) and ( iii )
A+B+C+D= 154 —-( iv )
Putting value of equation ( iv ) into equation ( i )
154 + E = 200
E= 200-154
E = 46
