Hi,
We are given that there are 26 paychecks in all. 6 paychecks each pay $750, and rest of 20 paychecks each pay $30 more than $750.
New avg= 750+(20*30)/26.
Now lets assume there were 30 paychecks in total. 6 paychecks each pay $750, and rest of 24 paychecks each pay $30 more than $750. ( i just picked a number that would cancel the 30 in the numerator)
By 20th paychecks the average would have increased by 21. How {(14*30)/20}=21
By 30th paychecks the average would have increased by 24. How {(24*30)/20}=24
So the new avg would be between 771 to 774
We have 773 as option
Hence Choice D .
