Line Chart Data Interpretation Questions for IBPS PO, SO, Clerk Exams - 1

Ans: A

Total number of watches sold in Town X in January, February, March and June = 120 + 140 + 180 + 240 = 680

Required average = $${680} / {4}$$ = 170.

Ans: B

The number of watches sold in Town Y in April = 210

The number of watches sold in Town X in April = 150

Required percentage = $${210 - 150} / {150} × 100$$ = $${60} / {150} × 100$$ = 40%.

Ans: B

Number of watches sold in Town X in the month of May = 180

Number of watches sold in Town X in the month of July

= $${180 × 110} / {100}$$ = 198

Number of watches sold in Town X in the month of January = 120

∴ Required ratio = $${198} / {120}$$ = $${33}/{20}$$ = 33 : 20.

Ans: C

Total number of watches sold in both the towns together in the month of June = 240 + 180 = 420

Total number of watches sold in both the towns together in the month of March = 180 + 150 = 330

Required difference = 420 - 330 = 90.

Ans: A

Number of watches sold in Town Y in February = 120

Number of watches sold in Town Y in May = 230

Required percentage increase

= $${230 - 120} / {120} × 100$$ = $${110}/{120} × {100}$$ = $${110 × 5}/{6}$$

= $${275}/{3}$$ = $$91{2}/{3}%$$.
