Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B) Only
(A) The difference between the total number of calculators sold by shops P and Q together in August and the number of calculators sold by shops R and S together in June is 42 Incorrect. The difference is 48, not 42:
P and Q in August: \(130+124=254\)
R and S in June: \(110+96=206\)
Difference: \(254-206=48\)
(B) The average number of calculators sold by Shop S in the three months is 92 Correct.
Shop S: \(96+94+86=276\), and \(276\div3=92\)
(C) The respective ratio between the total number of calculators sold by shops P and Q in July and the total number of calculators sold by shop Q in August is 45:31. Incorrect. The ratio is 47 : 31, not 45 : 31:
P and Q in July: \(100+88=188\)
Q in August: 124
\(188:124=47:31\)
