In a bag, there are a certain number of toy-blocks with alphabets A, B, C and D written on them. The ratio of blocks A:B:C:D is in the ratio 4:7:3:1. If the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks, what is the number of ‘B’ blocks?
Answer with explanationAnswer: Option D
Let the number of the blocks A,B,C,D be 4x, 7x, 3x and 1x respectively
=> 4x = 3x + 50
=> x = 50.
So the number of ‘B’ blocks is 7*50 = 350.
