A, B and C are batsmen. The ratio of the runs scored by them in a certain match are given below : A : B = 5 : 3 and B : C = 4 : 5. In all they scored 564 runs. The number of runs scored by B is:

A : B = 5 : 3
B : C = 4 : 5
∴ A : B : C
= 5 × 4 : 3 × 4 : 3 × 5
= 20 : 12 : 15
Sum of ratios
= 20 + 12 + 15 = 47
∴ Runs scored by B

=	12	× 564 = 144
	47
