Solution
The correct option is D 1336
Given:Number of bars Conall had = 36After selling 10 bars on his own,Number of bars remaining = Number of bars Conall had − Number of bars he sold on his ownNumber of bars remaining = 36 − 10
Number of bars remaining = 26
After his mother sold ha;f of the remaining bars,
Number of bars remained unsold = Number of remaining bars − Number of bars his mother sold= 26 − 262= 26 − 13= 13Number ofbars remained unsold = 13Fraction of Conalls bars remained unsold = Number of bars remained unsoldNumber of bars Conall had
= 1336Therefore, Fraction of Conalls bars remained unsold is ′1336′.
Given:
Number of bars Conall had = 36
After selling 10 bars on his own,
Number of bars remaining = Number of bars Conall had − Number of bars he sold on his own
Number of bars remaining = 36 − 10
Number of bars remaining = 26
After his mother sold ha;f of the remaining bars,
Number of bars remained unsold = Number of remaining bars − Number of bars his mother sold
= 26 − 262
= 26 − 13
= 13
Number ofbars remained unsold = 13
Fraction of Conalls bars remained unsold = Number of bars remained unsoldNumber of bars Conall had
= 1336
Therefore, Fraction of Conalls bars remained unsold is ′1336′.
