Choose the correct statements from the following. Choose the correct answer from the options given below.

1.X% of y is equal to y% of 100x

2.If 40% of 60% of 3/5 of a number is 504, then 25% of 2/5 of that number is equal to 350

3.If A is 15% more than B, then B is about 13.04% less than A

4.10% of 5 and 5% of 10 add up to 0.1

A1 and 2 only

B2 and 3 only ✓ Correct

C3 and 4 only

D1 and 4 only

Correct answer: (B) 2 and 3 only

Explanation

Statement 2 and Statement 3 are correct.

Statement 2: 0.4 x 0.6 x (3/5) x N = 504 gives N = 3500, and 0.25 x (2/5) x 3500 = 350.

Statement 3: A = 1.15B, drop = 0.15B/1.15B = 13.04%.

Statement 1 fails since x% of y = xy/100 but y% of 100x = xy.

Statement 4 fails since 10% of 5 + 5% of 10 = 0.5 + 0.5 = 1, not 0.1.
