Correct Answer: Only I
Solution :
I. The expenditure on article R by A = 80
The expenditure on Q by B = 70
Required percentage = $\frac{80-70}{70}×100$ = 14.28%
II. The average expenditure on articles P and Q by A = $\frac{40+60}{2} = 50$
The average expenditure on R and S by B = $\frac{90+50}{2} = 70$
Required difference = 70 – 50 = 20
⇒ II is correct.
Hence, the correct answer is only I.
