let us consider the bananas he ate of the 1st day be x
so
x+(x+6)+(x+12)+(x+18)+(x+24)=100
so by solving the above we get
x=8

5x+60=100
5x=40
x=8
first day=8
second day=x+6=8+6=14

For first day let consider as x num of bananas
2nd day 6+x
3rd day 12+x
4th day 18+x
5th day 24+x
so

24+x=100(given)
ans: x=76

• Aug 22nd, 2008

Let no of bananas he ate in first day be x

then x+(x+6)+(x+12)+(x+18)+(x+24)=100
5x=40

therefore man ate 8 bananas in 1st day

let the banana eaten by him on the first day be x. each day  he is eating 6 more than the first day. so x+(x+6)+(x+12)+(x+18)+(x+24)=100. solving this we get x=8. there fore the number of banana eaten by him on the first day is 8.

let he eat (x-12) banana on first day
then he will eat (x-6,x,x+6,x+12) on next four days
then according to condition;
x-12+x-6+x+x+6+x+12=100
5x=100
x=20
number of banana that he ate on first =20-12
=8

Consider the no of bananas he ate on day 1 as X;
Then no of bananas on day2 - X+6
On day3 - X+6+6=X+12
On day 4 - X+18
& on day 5 - X+24
So the equation becomes
X+(X+6)+(X+12)+(X+18)+(X+24)=100
5X+60=100
5X=100-60=40
x=40/5=8.

Why did you stop with X+24?

#### meenakshi gupta

• Nov 27th, 2015

let the person eat x-12,x-6,x,x+6,x+12 in 5 days
then 5x=100
x=20
so first day will be 20-12 ie 8 ans.

x+(x+6)+(x+12)+(x+18)+(x+24)=100
5x+60=100
5x=100-60
x=40/5
x=8.
so he ate daily 8 bananas

100/5=20
avg of all term in AP middle term so,
1.2.3.4.5 the middle term=1+5/2=3 on third day he ate 20 bananas,
so 1 2 3 4 5
8 14 20 26 30
so on 1st day he ate 8 bananas

#### vinod raj

• Jul 26th, 2016

On the first day he would have eaten 76 bananas
2nd day= 82 (76+6 more then the previous day)
3rd day = 88 (82 + 6 more than previous day)
4th day = (88 +6) 5th day (94 +6 == 100 reached)

#### Dharmishtha

• Jul 28th, 2016

x+(x+6)+(x+12)+(x+18)+(x+24)=100
so now
6+12+18+24=60
then 100-60=40
40/5=8
so on the first day he eat 8 bananas
and so 8, 14,20,26,32=100

x + (x+6) + (x+12) + (x+18) + (x+24) =100
5x + 36+24 = 100
5x = 40
x = 8
