The ratio of A and B in an alloy is 2 : 5. If the alloy is made of only A and B, how much amount of B will be there in 210 kg of that alloy?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 150 Kg.

Given:

A : B = 2 : 5

Let the amount of A and B in the alloy is 2x and 5x respectively.

Now, in 210 Kg of the alloy, ratio of A and B is

2x + 5x = 210

7x = 210 

x = 210/7 

x = 30

Now, the amount of B = 5x = 5 × 30 = 150.

Hence the amount of B in 210 Kg alloy is 150 Kg.
