Detailed Explanation & Answer
A. x% of y = y * x / 100 = yx/100
y% of 100x = 100x * y / 100 = xy
Statement A is not correct.

B. Let's assume the number N
Given, N x (3/5) x (60/100) x (40/100) = 504
N = 3500
Given, N x (2/5) x (25/100) = 350
N = 3500
Statement B is correct

C. Let's assume B = 100x then A would be = 115x
Their difference = 15x
The difference would be how much percentage of A?
15x * 100 / 115x = ~13.04 %
Statement C is correct

D. 10% of 5 = 5 x 10 / 100 = .5
5% of 10 = 10 x 5 / 100 = .5
Adding them = 1
Statement D is incorrect
A. y का x% = y * x / 100 = yx/100
100x का y% = 100x * y / 100 = xy
कथन A सही नहीं है.

B. आइए संख्या N मान लें
दिया गया है, N x (3/5) x (60/100) x (40/100) = 504
एन = 3500
दिया गया है, N x (2/5) x (25/100) = 350
एन = 3500
कथन बी सही है

C. मान लीजिए कि B = 100x है तो A = 115x होगा
उनका अंतर = 15x
अंतर A का कितना प्रतिशत होगा?
15x * 100 / 115x = ~13.04 %
कथन C सही है

डी. 5 का 10% = 5 x 10/100 = .5
10 का 5% = 10 x 5/100 = .5
उन्हें जोड़ना = 1
कथन D ग़लत है
