Question 5 of 5

5. Question

When 60% of a number A is added to another number B, B becomes 175% of its previous value. Then which of the following is true regarding the values of A and B?

Correct

Ans-d

B+ 60% of A = 175% of B → 60% of A = 75% of B.

0.6A = 0.75B

A/B = 5/4

Apparently it seems that A is bigger, but if you consider A and B to be negative the opposite would be true.

Hence, option (d) is correct

Incorrect

Ans-d

B+ 60% of A = 175% of B → 60% of A = 75% of B.

0.6A = 0.75B

A/B = 5/4

Apparently it seems that A is bigger, but if you consider A and B to be negative the opposite would be true.

Hence, option (d) is correct
