Question

A baker has 400 kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24kg each day? Show your calculations using the formula for Tn of an arithmetic sequence.

Answer 1

Step-by-step explanation:

Here,

Flour used on first day=0...given

Flour used every day except first day=

24 kg...given

Flour used till 3rd day=flour used on 2nd day +24 kg=48 kg.

A.P. is 0,24,48,...

a=0

d=48-24=24

tn=a+(n-1)d

t17=0+(17-1)24

t17=16×24

t17=384

Therefore flour used till 17th day is 384kg.

Remaining flour on 17th day=400-384=16kg

16kg of flour will be left on 17th day.
