Show Answer

Correct Answer: (5)

Solution: (5)

Per cent of wallets of both types sold by stores B, C and E=(33.5+10+23.5)% =67%

Their number =4200×67100 =2814

Number of tri-fold wallets sold by these stores =(24+15+21)% of 1800 =1800×60100=1080

∴ Number of two-fold wallets = 2814−1080=1734

∴ Required average =17343 =578
