The sum of three numbers A, B and C is given as 3500. If the ratio of A to B is 2:3 and the ratio of B to C is 4:5 then what is the value of B?
Show answer & explanation
Correct answer: A
Explanation
Given:
A + B + C = 3500
A : B = 2 : 3
B : C = 4 : 5
LCM of B = 12
A : B = 8 : 12
B : C = 12 : 15
A : B : C = 8 : 12 : 15
Total division = 8 + 12 + 15 = 35
B = (12/35) × 3500 = 1200
